Cortical centers of the parietal lobe of the brain.

In this article you can find out what the head areas are, how this part of the body is structured and why did it appear during evolution in the first place? The article begins with the simplest thing - basic information about the organization.

What is meant by the skeleton of the head or, more simply, the skull? This is a collection of many bones, paired or not, spongy or mixed. The skull contains only two large sections:

• cerebral (the cavity in which the brain is located);
• facial (this is where some systems, such as the respiratory or digestive, originate; in addition, more sensory organs can be found here).

As for the brain region, it is worth mentioning that this area is divided into two:

• cranial vault;
• its foundation.

Evolution

It is important to know that vertebrates did not always have such a large head. Let's dive a little into the past. This part of the body appeared in ancient vertebrates during the fusion of the first three segments of the spine. Before this phenomenon, the same segmentation was observed. Each vertebra had its own pair of nerves. The nerves of the first vertebra were responsible for smell, the second for vision, and the third for hearing. Over time, the load on these nerves increased, it was necessary to process more and more information, which led to the thickening of these segments responsible for these sense organs. So they merged into the brain, and the union of the vertebrae formed the brain capsule (like a skull). Note that even the modern human head is still divided into the segments from which it was formed.

What is the average size of an adult's head? Length - 17-22 cm, width - 14-16 cm, height - 12-16 cm, circumference - 54-60 cm. The length of the head is usually greater than the width, so it is not round, but elliptical. It is also very interesting that the numbers (length, width and height) are not constant, they either increase or decrease. And all this depends on the location of the person.

Parietal Center

Biological correspondence: pineal gland and brain structures responsible for long-term memory. This center is mainly associated with the work of realizing the function of self-awareness. The key word for him is the word “INSPIRATION”. This word is associated with the meaning and purpose of life. Finding answers to questions such as: Who am I? What is the meaning of my life? How to live correctly? generates mental pressure, which is expressed through confusion, doubt and a feeling of incomplete understanding of oneself and the world. Therefore, this center is responsible for directing attention, that is, it filters incoming information in accordance with the ideas and views of the world that it is currently inspired by. Important information is recognized and remembered, while the rest goes into long-term memory. Life energies function in the body, and the process of self-awareness works in the mind. The needs of the existence of the body, that is, food, drink, shelter, procreation, etc., have a very large influence in the structure of consciousness and self-awareness. Therefore, very often consciousness is inspired by the ideas of owning specific objects and the desire to take an advantageous position in society. Self-awareness of myself as a separate object already draws a boundary between me and everything else. Because of this, the sense of the wholeness of the world is undermined. The constant concentration of consciousness on things of the material plane leads to separation from the phenomena of the entire surrounding world. Thus, ignorance about the real situation is created. By making decisions based on ignorance, a person will quickly harm himself. Inspired by the idea of ​​possessing a specific object or social status, a person psychologically takes on the properties and qualities of this object. That is, he ceases to be himself. Over time, moving from one inspiring idea to another, a person will change the principles of life and the nature of relationships with the outside world. He is completely lost in the variety of his hobbies. The center of inspiration is vital for a person. If inspiration disappears, then interest in life disappears, and the person dies. The pursuit of possession of things and status leads to exhaustion of the body and does not provide satisfaction, since a person constantly moves away from himself. Such victories cease to inspire, and, as a result, interest in life is lost. Mental inspiration creates pressure on the mind to think and create concepts of the world and itself.

This center is identified in approximately 30 percent of people. A certain center gives the potential for original thinking and perspective on the world around us. A person with a certain parietal center has the ability to inspire others, inspiration comes to him in a fixed way. He also has a fixed way of dealing with mental pressure. If the center is not defined (70% of people), then the vast majority of thoughts and questions in the human mind, as well as mental inspiration, comes from outside, from others. So he constantly thinks about things that don't matter to him, and his head is filled with questions that don't belong to him. This creates mental pressure and can create stress and anxiety. In an attempt to free himself from pressure, a person tries to answer them all, although only a few of them actually matter to him. Thus, a person can get stuck on other people's questions, sometimes for a long time. If we consider the characteristics of spiritual development, then people with a certain parietal center can find a connection with the “Heavenly Father” or some other response from entities of the spiritual plane that resonate with its innate frequency. It will be natural for a person with an undefined center to seek wisdom and a state of Clear (Pure) Mind. Both types of people can fall under the influence of the surrounding social attitude and become fanatics of a certain spiritual idea, seek a connection with a spiritual essence (the image of God) that does not correspond to its natural certainty, or try to clear the mind of thoughts by violent methods in order to achieve a state of Emptiness. If the parietal center is identified, then it is not at all necessary to reject the spiritual concepts that dominate the person’s environment. As a rule, spiritual movements have many interpretations of God and the Spirit, and within the framework of the accepted religious and spiritual tradition, a person will be able to find interpretations that are consonant with him. But it is also possible to escape into ideas about God and the World that will seem exotic to those around him. If the parietal center is not defined, then it is better for a person to achieve the wisdom potential inherent in it. That is, one must realize that all the concepts that he encounters in his life are simply the worldview of other people. He can look at these concepts like clouds passing through the sky.

Confusion and doubt in the parietal center can give rise to an unhealthy desire to find answers to tormenting questions and initiate a race for these answers (search for a Guru, new theories, etc.). The answer to the questions about Who I am, what is the meaning of My life and what is My place in it, is found by the person himself, living his life in accordance with his certainties. The answers mature in the mind, just as a tree grows from a seed. This requires time and careful care. And for this to happen, you must live YOUR life, and not the life of a person in general, in accordance with the homogenized concepts of the surrounding social environment. Living HIS life, a person with a certain parietal center will be in tune with exactly that “Heavenly Father” who is in tune with him. And a person with an undefined parietal center will find the best way to clear his mind. Therefore, the search for spiritual growth cannot be separated from everyday life, in which we manifest ourselves. In the ordinary consciousness of a person who is guided by homogenized concepts, his False Self of the Parietal Center will generate the following kind of conversations within the consciousness: “I need to find inspiration in something that will make life meaningful. Maybe if I go there I'll find inspiration. I need to find answers to my questions. Where can I find answers? Who knows the answers? I need to understand this and find meaning in it. Where should I go and who should I talk to to find answers?” If the Parietal Center is defined, then its natural state creates mental pressure to comprehend and understand things. He knows that confusion, doubt and clarity are a natural process. Knows that these processes have their own internal timing and resolution. Such a center has the ability to uplift and strengthen others with inspiration, insight and understanding. Under pressure from the False Self, this center turns mental pressure on itself, which leads to deep anxiety, self-doubt and depression. He tries to relieve pressure through action, which leads to rash and inappropriate mental decisions. A person is unable to remain patient, which leads to missed opportunities for inspiration. The Vague Parietal Center in its natural state explores ideas and inspiration coming from different directions. He is open to the wonder of the unknown and uncertainty, does not act under mental pressure and does not take on the pressure of other people's need to find answers to their questions. The person enjoys the pressure to learn more without identifying with it, and does not suffer from confusion and doubt, trusting that clarity will come or not. Under the influence of the False Self, a person is easily lost in doubt and confusion or feels overwhelmed by it. He tries to resolve other people's issues by taking on other people's concerns. Tries to relieve mental pressure by taking action. In difficult situations, this leads to loss of focus.

False Self Strategy in the Parietal Center: Think about what doesn't matter. The peculiarities of the functioning of the Parietal Center in everyday life can be understood by taking into account its following features. The parietal center is not entirely located in the body.
It is sometimes in the body and sometimes not. There are many people who have experienced clinical death when they looked at themselves from above. This is part of the same process. So one of the strange things about the nature of our consciousness is that one of our centers is literally outside the body, outside the flesh, but not outside the aura. We have a neocortex, the outer layer of the cerebral cortex, which is very important to us because it is the seat of our reflective consciousness. It is where we can identify with our worldview, where we can actively process what we imagine is happening to us. There is a bridge between the gray matter of the brain and the cerebral cortex, which is also a boundary, or threshold. The guard at the threshold is the pineal gland, and that is why it is connected to the Parietal Center. The pineal gland does some interesting things in our lives. First of all, it functions like a sponge. If you have a sponge with no liquid, it is open. Once filled with liquid, it will literally close and nothing will be able to penetrate through it because it will no longer be porous. Likewise, the pineal gland, like a sponge, can open up and be porous, allowing passage through, or it can harden, not allowing anything to pass through. When your pineal gland closes, you fall asleep. If you are given anesthesia in the hospital for surgery, it goes directly to the pineal gland, which instantly closes it and you lose consciousness. When we perceive the world, it goes to the deep gray areas through the pineal gland. He walks, carefully looking around, and then goes out again. When it comes out, we call it inspiration. Acting as a border guard, the pineal gland allows information to pass from the gray areas to the cerebral cortex - this is its job. Thus, inspiration is your own experience in the world, building up as pressure in the gray matter, which then must be released. The only way to release it is through the pineal gland as a pressure that feeds the Ajna center (mental concepts), feeds your conceptualization process. As humans, we live in a pressure sandwich. At the very top of the Bodygraph is the Parietal Center (pressure of self-awareness), and at the very bottom is the Root Center (pressure of the flow of life), both are centers of pressure. The parietal center is the pressure of inspiration, and this pressure is often difficult to deal with. It can bring a lot of mental anxiety. Inspiration is always connected with what is not captured, not understood. Doubt, confusion and true surprise emerge from the Parietal Center as a field of inspiration. Once the Parietal Center is identified, it creates pressure on the Ajna conceptualization system, pressure to find meaning, understand and recognize what this inspiration is associated with. Inspiration is rooted in our visual and aural lives, and comes from within as a result of experience. You see or hear something and it passes through you. Suddenly it comes back as a question and you are trying to find an answer or make sense of something that is confusing you. Or it comes back and you find yourself trying to rationalize and find out what it really means. This creates pressure that can lead to concerns about whether one can explain clearly to another, whether one will make another understand what one means, or whether one can stimulate someone else with an idea. In our human form, we operate as a mechanism in the present moment. Regardless of our ability to perceive the present, our entire form experiences the moment on many different levels. It absorbs not only what is obvious, for example, what you see, smell, hear, touch, but the taste of the air you breathe, etc. The brain is structured in such a way that the physical workshop and the power of its storage device, memories are endless. One of the miracles of our mind is that it just keeps remembering. This doesn't mean you have access to it all; it just means it keeps storing because it stores literally everything in the space. Since information is not stored, so to speak, physically (it is associated with the work of the field structures of the body), the power of the storage device is limitless and infinite. Taking in all this information every moment, every second of every day is what inspiration is. We take a “breathe in”; Every moment we inhale, absorb all space and store it endlessly in the field space of our brain. Inspiration is not something that comes from above or from below. It is clearly a by-product of our very existence as we take it all in for inspiration. Our brains are designed in such a way that there is a little piece at the front that says, “Hi, it’s me.” Everything else that processes the data is hidden behind. You never meet anyone who works in this department because they are all in the big gray processing corridors. The gray area of ​​your brain makes up about 90% of your brain mass, and you have no conscious access to it. All the information that you perceive with every breath you take is literally the prana of consciousness. You inhale it and store it in these deep gray areas. It creates pressure because since you absorb it, you are created to do something with it, because we are born to process the field of consciousness. To be more precise, our memory is connected to the field structure that surrounds our body. The gray matter of the brain cannot accommodate all this volume of information. It can serve as switches and access pointers. As centers of pressure, the Parietal and Root centers have a deep commonality because they are both the fuel for essential human processes. But at the same time, they are very different for one very simple reason - the Root Center is a motor (adrenaline pressure). The fuel of the Root Center as a motor is different from the Parietal Center. The motor can initiate action, but the centers of consciousness that are not motors cannot. The parietal center creates mental pressure - and nothing more, and this gives us a deep understanding of the nature of the mind or Ajna center. Trapped in this sandwich of no-motor, with the Parietal Center on top and the Throat Center below, the mind is not made to manifest activity because it is not fueled by the motor's fuel. And this tells us something essential about the nature of the mind - it is created only to manifest speech and communication. The impact on us and those around us is carried out using other natural mechanisms. This is the process of bringing the light down to the level of sound when it reaches the Throat. Information moves along the circuits in such a way that each of these centers perceives information at a certain frequency. They then descend to the biological connection, which actually realizes the potential of this information in the physical body or leads to realization. For example, when the pineal gland is open, it can allow serotonin, which is a special chemical messenger, to go from the cerebral cortex into the deep gray areas. This makes the pineal gland very important to us as it allows us to access what is stored in the deep gray areas or on our “hard drive” to use a computer analogy. How this information is stored and how it is retrieved is an area of ​​extensive scientific research. But we know that our self-reflective consciousness in the cerebral cortex needs to draw in the context of this gray area, although it is the neocortex that gives it shape. In other words, you don't get sentences, whole thoughts, or complete concepts. That is, unless you decode them, you don't know what they are. 70% of humanity has an open Parietal Center, meaning that only the remaining 30% with a defined Parietal Center produce the frequency that we all perceive. Thus, 70% of the population thinks about things that do not directly concern them. With an open Parietal Center, you think about things that are naturally attractive to you because they are not at all what you would think about on your own. Instead of ignoring this attractive conditioned pressure from the outside, the False Self of the open Parietal Center constantly flies away in many different directions. Remember how pressure from the Parietal or Root centers moves all the energy along the circuit? The pressure from the Parietal Center and the pressure from the Root Center are very different for the obvious reason that one center is a motor and the other is not. Being under the pressure of active adrenaline (Root Center) is completely, completely different from being under the pressure of a concept (Parietal Center). What is the pressure of the Parietal Center? Any person with an open center of pressure wants only one thing - to get rid of this pressure. This is why people with an open Root Center often do everything very quickly. Of course, if they are incorrect, they will be quick and will be wrong. But they are very fast because they want to get rid of the pressure. And of course they can't - that's the joke, and if you have an open center of pressure, you'll know it. But every time you are under pressure, you want to get rid of it. And the same with the Parietal Center. For example, if you are attracted to a question, and the question is a pressure, you cannot get rid of that pressure until you find the answer. He will harass you and you will want to get rid of him. Most False Selves will get rid of it by any means possible. There are three types of mental pressure. One is the pressure of logical doubt, which is the pressure of fear of the future. You have a question, and it does not need to be formulated or understood as a question in any way - it is a doubt. This pressure only arises when the security of the future gives rise to concerns. Then it arises instantly. Until you deal with this pressure, it will not go away, and you will become more and more afraid that something will go wrong. You have that nagging feeling that something is going on and you need to find a solution. People will appear and give you the formula, saying, “No, no, no. Everything will be OK. Don't worry. Tomorrow it will happen and everything will be fine. You needn't worry." But until this is resolved, the pressure will remain, and you will want only one thing - to get rid of it. The False Self finds solutions that can force a person to act, but most likely everything will go to waste, simply because he wants to do everything as quickly as possible. On the emotional side, the pressure is confusion, and you don't like being confused about the past. Something in the past is bothering you, but you don't know exactly what it is, but it's bothering you. Until you find some meaning in it, it will remain in you as a disturbing pressure. You only want solutions. A person wants to get rid of this pressure that sorts the past. On an individual level, mental pressure is something you should be aware of. But you cannot generate or practice knowledge. It is not about developing a pattern or seeing what the future is. The essence of knowledge is not remembering details in the past in order to see continuity. You can only know when you know. These people, under the pressure of the need to know, can literally go crazy, because knowledge may never happen. This is a mutation process. It may never happen. You can spend your whole life with this thing in your head. "I must know God." You may need to learn something, but that doesn't mean it will ever happen. Knowledge either exists or it doesn’t. For the vast majority of people, there is no one who can give them correct solutions. Because the questions are not truly meant for them, there is no mental peace on the planet. The False Self's strategy is to worry about issues that don't matter. The open center will always be attracted to what it is not, but it cannot be the source of your decisions. When someone with an open Parietal Center enters the aura of a person with a certain Parietal Center, he will be inspired. He might experience a certain level of confusion, and there is no sustainable way for him to work through this confusion. When another person leaves his aura, he may be left with these nagging questions that he cannot answer. The more he tries to find answers, the more frustration he experiences. If you do not understand your conceptualization process, the resulting anxiety may lead you to make false assumptions about your mental state. Conditioning is not the enemy. The enemy is ignorance about conditioning. Any conditioned field can have a positive impact; however, it will always be impermanent and therefore unreliable. If you have an open Parietal Center, then someone may put mental pressure on you, and you will think about some particular dilemma that needs to be resolved. But if it is not your dilemma and it is not your authority, then it is not your responsibility to carry the weight that you cannot solve it. A person with an undefined Parietal Center, not suffering from the conditioning of this open center, has the potential for wisdom in recognizing what inspiration can be valuable. Who can truly inspire? Such a person can admit it. When one no longer gives authority to these open centers, there can be a great advantage in them. When we extrapolate this to a larger segment of the population, we can see people who have been rushing forward uncontrollably for the last 250 years, trying to solve mysteries. We live in a world where millions of people on this planet are seeking spiritual inspiration. There have never been such quantities before, and it's all a byproduct of mental pressure. 70% of people with an open Parietal Center fuss, thinking about things that will not change their daily life, for example, eliminating the need to take out the trash. An open Parietal Center will pay more attention to something that doesn't matter because that's what attracts it the most. Important things will be ignored because they do not attract the open Parietal Center, so these people give their attention to something else while their life passes them by. ___________________________________________________

CHAPTER 3 - HEAD AND ROOT CENTERS

Where does this stress come from?

At the very top of the Body Graphics is the Head Center. At the very bottom of the Body Graphics is the Root Center. These are Pressure Centers . To be a human being is to be under constant pressure.

The Head Center is the Center of Inspiration. Dealing with the pressure of inspiration is often not easy. It can bring a lot of anxiety, mental restlessness. Inspiration is always about what has not been understood. Here is doubt, here is confusion, and here is a real miracle, and this is how inspiring fields emerge from the Center of the Head. The moment this inspiration is present, in other words, the moment the Head Center is defined - and it can only be defined if it is connected with the Ajna Center - it creates pressure on the conceptual system to either find meaning, or understand, or know, what this inspiration is.

Inspiration is rooted simultaneously in our visual and acoustic lives. In other words, inspiration comes from within as a result of living experience. You see something, you hear something, it goes through you, and at some point it comes back to you as a question. It comes back as an attempt to make sense of something that seems confusing. This comes back as an attempt to rationalize, an attempt to find out what it really means. This creates pressure that can lead to deep anxiety. Worry about whether you can successfully explain yourself to someone else. Will you be able to reasonably convey your understanding to someone or will it be possible to stimulate someone with your idea.

The pressure emanating from the Head Center feeds our mental restlessness. One of the most common configurations in design is when the Head Center is connected to the Ajna Center, but not connected to the Throat Center. When the pressure of the Head center is working, there is a deep need within the Ajna Center to realize the conceptualization to get rid of this pressure.

Often these people experience discomfort. They suffer from headaches. They suffer from migraines. They feel enormous pressure on themselves.

The center of the Head corresponds to the pineal gland. It is a way out of the deep gray areas of our brain into the neo-cortex. This is revealed in the Ajna Center, where our main endocrine glands are located in the functioning of our entire bodily system.

Once you grasp a concept, the real worry is whether you will be able to express it. If you don't have a constant connection with the Throat, you will never be able to say WHAT you want to say, when you want to say it.

The Root Center is the motor. It is the only one of the four motors that does not have direct access to the Throat. The Root Center corresponds to the adrenaline system and stress hormones. This is a system of physical pressure, especially if we consider its special connections with the Sacral Center. These three channels create three formats of energy. They produce the main frequencies through which we operate. We have a cyclical process. logical focusing process and mutational process In addition, the Root Center establishes the pressure to “emotionalize,” to feel, (its connection to the Solar Plexus) and the pressure to be healthy (its connection to the Immune System. Spleen)

An undefined Root Center, as well as an undefined Head, can come under enormous pressure. Remember that when the Center is not painted, when it is white, it is not only vulnerable, but also increases any impact on it. Someone with an undefined Root Center may end up being overactive as a result of conditioning with predictable consequences.

The importance of Human Design in family life, the mechanics of family relationships are extremely important, especially for children. Imagine a child with an undefined Root Center. Friends will come to this child. We are always attracted to what we are not. An indefinite or open Center always attracts a definite one. At the moment when a friend comes to him and “picks up” a child with an undefined Root Center, the result of an increase in root energy can be explosive. This child will be very overstimulated. This could be a problem.

In a school where in each class children become defined in all their centers by the aura of the class, a child with an undefined Root Center will be under abnormal pressure and stress. The result will be intense anxiety that will be misinterpreted. It's not the child's fault. But he will be punished, he will be humiliated, he will be taken to psychotherapists.

There are a huge number of children who do not have certain motors. Many of them undergo psychotherapy courses. They were misdiagnosed with hyperactivity and hyperexcitability. But this is not true. When they are educated about the nature of their Design and how to live with it, then they will not identify with and give authority to energy that is not theirs. They will be able to take advantage of this energy, but they will not lose control under its influence.

The same is true for the undefined Head Center and its conditioned pressure. When he enters someone's specific Head Center, he will be filled with inspiration. He will be filled with a certain level of puzzlement. He doesn't have a consistent way of working with it. When a person with a certain Head comes out of his aura, he is left with questions stuck in his mind that he cannot answer. And the more he tries, the more upset he gets. If he does not understand the mechanics of the conceptualization process, then anxiety may lead to false assumptions about his mental state.

Conditioning is not the enemy. The enemy is ignorance of conditioning. Any conditioning field can bring positive influence. However, it will always be impermanent and as such unreliable.

Falling under conditioning pressure, the indefinite Kornev. He is frozen by the surrounding strong adrenaline energy - the “freezing” stage. The Undefined Root Center will either love the crowd, or, conversely, be terrified of the crowd. He will either ride on the adrenaline that is increasing in him and take advantage of this increased energy, or he will always avoid crowds for fear of being overwhelmed by this energy.

It is important to realize that we cannot afford to give authority to something that we are not. In other words, someone can put pressure on us on a mental level to think about solving a problem. But if it is not our problem, and it is not our authority, then it is not our responsibility to bear the burden of a problem that we cannot solve.

The same is true for the uncertain adrenal system. A person should not lose himself under pressure. He can take advantage of it or avoid it. All this concerns

friends will come to this child. We are always attracted to what we are not. An indefinite or open Center always attracts a definite one. At the moment when a friend comes to him and “picks up” a child with an undefined Root Center, the result of an increase in root energy can be explosive. This child will be very overstimulated. This could be a problem.

But if it is not our problem, and it is not our authority, then it is not our responsibility to bear the burden of a problem that we cannot solve.

The same is true for the uncertain adrenal system. A person should not lose himself under pressure. He can take advantage of it or avoid it. It's all about recognizing what you are not. By recognizing what you are not, you can break your dependence on it. The result is your potential wisdom.

A person with an undefined Head Center, not suffering from the conditioning of that center, has the potential wisdom to recognize what inspiration is truly valuable. Who can really inspire. He is the one who can recognize it. Likewise, an open Root Center can understand the nature of stress and how it works. The great advantages of these vague Centers are revealed when man does not give them authority.

In my Design the Emotional System is not defined or open. I have been teaching people about emotions for over ten years. Through my open Solar Plexus center I experienced the full emotional spectrum. For a long time in my life, before I understood my mechanics, I gave authority to emotions that were not mine. I've been through chaos in my personal life, and I've been through chaos in my professional life. By understanding my mechanics, I no longer assign authority to something that I am not. I'm good at this. Along with understanding came wisdom about the emotional plane.

This dichotomy within us: Definite Centers - Uncertain Centers, is a great challenge, and yet brings the greatest rewards. She brings invaluable knowledge. Knowledge that is valuable not only for the person himself, but also for other people.

As human beings we are constantly under stress, that's a fact. We are stressed because it is necessary to stay alive and to be healthy in this life. We are also under pressure to be able to communicate with each other essential things about what it means to be human. This is our fundamental pressure.

Brain

Before moving on to studying the areas of the head, it is worth saying that the head is considered the most important part of the body for a reason. After all, this is where they are located:

Now we will learn a little more about the brain. What is it and how does it work? This organ is formed from nerve fibers. Neurons (these are brain cells) are able to control the functioning of the entire human body by generating an electrical impulse. In total, twelve pairs of nerves can be observed that control the functioning of organs. Signals sent by the brain reach their destination through the spinal cord.

The brain is kept in fluid all the time, which prevents it from contacting the skull when the head moves. In general, our brain has pretty good protection:

The liquid in which our brain “floats” is called cerebrospinal fluid. The pressure of this fluid on the organ is considered to be intracranial pressure.

It is also important that the work of the brain and organs located on the head requires large energy costs. For this reason, we can observe intense blood circulation in this area. This:

1. Nutrition: carotid and vertebral arteries.
2. Outflow: internal and external jugular veins.

So, at rest, the head consumes about fifteen percent of the body’s total blood volume.

Skull and muscles

The skeleton of the head (skull) has an equally complex structure. Its main function is to protect the brain from mechanical damage and other external influences.

The entire human skull is formed by 23 bones. They are all motionless except for one - the lower jaw. As mentioned earlier, two departments can be distinguished here:

Bones related to the facial section (there are 15 in total) can be:

Paired bones of the medulla:

Unpaired:

The entire brain section consists of a total of eight bones.

The cervical region, to which the skull is attached, allows the head to move. Movement is provided by the muscles of the neck. But on the head itself there are also muscle fibers that are responsible for facial expressions, one exception is the masticatory muscles, which are considered the strongest in this area.

Why does everyone get a headache from time to time?

This is true. Everyone is familiar with this disease, regardless of the location of the pain - in the frontal part, back of the head, ears, temples; for example, with a migraine, one half of the frontal part or one temple most often hurts. There are always reasons why a headache occurs, it’s just that a person cannot always associate them directly with the illness. Problems can arise due to exposure to any viral disease, strained neck muscles in the spinal area, weather changes or stress. In women, headaches (in the frontal part, the back of the head, in the temples or ears) can occur in connection with the menstrual cycle; the causes of the disease are often hidden behind incorrectly selected glasses, high blood pressure... In these cases, a headache (in the frontal part, the back of the head ) is a symptom of another, primary, problem and is accompanied by other manifestations (nausea is often present), of which there can be a large number. In cases where a headache (in the frontal part, back of the head, etc.) is accompanied by other symptoms, such as nausea, severe dizziness, a condition where one temple or eyes hurt, it is advisable to consult a doctor who can determine the causes of the disease .

Head areas

The entire head is conventionally divided into 13 regions. There they also distinguish between paired and unpaired. And so, six of them are classified as unpaired regions.

1. The frontal area of ​​the head (attention is focused on it in the next section of the article).
2. Parietal (detailed information will be presented to your attention later).
3. Occipital (discussed in more detail in a separate section of the article).
4. Nasal, which completely matches the contour of our nose.
5. Oral, also corresponds to the contour of the mouth.
6. The chin, which is separated from the mouth by the geniolabial groove.

Now we move on to listing the seven paired areas. These include:

1. The buccal region is separated from the nose and mouth by the nasolabial groove.
2. Parotid-masticatory (contours of the parotid gland and muscles responsible for the chewing reflex).
3. The temporal region of the head (the contours of the scales of the temporal bone, located below the parietal region).
4. Orbital (outline of the eye sockets).
5. Infraorbital (below the eye sockets).
6. Zygomatic (cheekbone contour).
7. Mastoid (this bone can be found behind the auricle, which, as it were, covers it).

Frontal region

Now we move on to a detailed examination of the frontal region of the head. The boundaries of the anterior section are the nasofrontal suture, the supraorbital edges, the posterior section is the parietal region, the sides are the temporal region. This section even covers the scalp.

As for the blood supply, it is carried out through the following arteries:

They arise from the ophthalmic artery, which is a branch of the carotid artery. A well-developed venous network is observed in this area. All vessels of this network form the following veins:

The latter, in turn, partially flow into the angular and then into the facial veins. And the other part goes into the eye.

Now briefly about the innervation in the frontal region. These nerves are branches of the ophthalmic nerve and have names:

As you might guess, they pass together with the vessels of the same name. Motor nerves are branches of the facial nerve called temporal.

Parietal region

This area is limited by the contours of the bones of the crown. You can imagine it if you draw projection lines:

Blood supply is facilitated by arterial vessels, which are branches of the parietal branches of the temporal artery. The outflow is the parietal branch of the temporal vein.

Innervation:

Occipital region

The occipital region of the head is located below the parietal region, and is limited to the posterior region of the neck. So, the boundaries:

Arteries contribute to blood supply:

The outflow is the occipital vein, and then the vertebral vein.

Innervation is carried out by the following types of nerves:

What fields are included?

• Field 3,2,1 – primary somatosensory fields. Located in the postcentral gyrus.
• Field 4 - motor area - is located within the boundaries of the precentral gyrus
• Field 5 – secondary somatosensory area
• Area 6 – secondary motor area
• Area 7 is the tertiary motor area. Located in the upper parts of the parietal lobe (between the postcentral gyrus and occipital lobe)
• Field 39 – center of the visual analyzer of written speech
• Field 40 – motor analyzer of complex skills

Nervous system

The article briefly talks about the nervous system of some areas of the human head. From the table you will find out more detailed information. In total, the head contains 12 pairs of nerves, which are responsible for sensations, the secretion of tears and saliva, the innervation of the muscles of the head, and so on.

Safe medications and pills

When planning a visit to the doctor, the patient should be prepared to answer questions about how often pain occurs and what its intensity is. This will help the doctor develop the correct treatment tactics.

Groups of drugs effective for episodic attacks of pain

Medicines to treat this pathology are non-steroidal anti-inflammatory drugs (NSAIDs). They have an analgesic effect, relieve inflammation, and eliminate swelling.

Often prescribed:

• Ibuprofen-400 mg per day;
• Ketoprofen-100 mg/s;
• Naproxen-500 mg/s;
• Meloxicam-7.5-15 mg/s;
• Celecoxib-200 mg/s.

Most NSAIDs have a negative side effect: with long-term use, they negatively affect the organs of the gastrointestinal tract, including the development of drug-induced gastritis.

Medicines Meloxicam and Celecoxib are new generation drugs that do not have a negative effect on the gastrointestinal tract. The disadvantages of using these drugs include the relatively high price.

Analgesics are often used at home to relieve an attack. They do not treat the disease, but only relieve pain. Drugs in this group are suitable for stopping episodic attacks, but their systematic use leads to the occurrence of abuse syndrome.

During an attack of pain, you can take Paracetamol-100 mg, Citramon, Analgin-500 mg or Mig 200-400 mg.

If the examination revealed the appearance of cephalgia after exercise as a result of increased blood pressure, the doctor will prescribe medications prescribed at an early stage of the development of hypertension. These include: vasodilators, ACE inhibitors, diuretics, calcium channel blockers.

Self-prescribing antihypertensive drugs is unacceptable. Self-medication leads to serious consequences.

For muscle tension, drugs from the group of muscle relaxants are used as part of complex treatment. They relax the spasmodic muscles of the head and neck, relieving pain of a spastic nature, and help restore blood flow.

Often prescribed:

• Mydocalm-150-450 mg per day;
• Sirdalud (Tizanidine) - 4 mg/s;
• Baclofen-15 mg/s.

Nootropic drugs are often prescribed as part of complex treatment: Phenibut, Nootropil, Glycine. Nootropics have an activating effect on brain function and increase its resistance to damaging factors. The drugs improve cerebral circulation and eliminate the consequences of traumatic brain injuries.

Sedatives in combination with basic drugs lead to muscle relaxation and decreased vascular tone. Taking tranquilizers helps relieve pain, but this type of medication quickly causes drug dependence with withdrawal symptoms.

Sedatives that are not addictive: Afobazol, Atarax; alcohol tinctures of valerian, motherwort, Maryina root.

For severe attacks, a combination of drugs is used: Sirdalud 2 mg + Aspirin 500 mg or Analgin 250 mg + sedative.

The use of vitamin B complexes has proven itself. Vitamins B1, B6, B12 have a beneficial effect on the central nervous system and restore the structure of nerve tissue. Vitamin complexes are often prescribed: Neuromultivit, Milgamma, Neurovitan.

If attacks of pain recur more than 10 times a month, a course of treatment with Ibuprofen at a dose of 400 mg per day for 2-3 weeks and treatment with muscle relaxants is prescribed for 2-4 weeks.

There is no single scheme for pain relief. Depending on the cause, each patient needs an individual selection of drugs.

Treatment of chronic disease

Sometimes cephalalgia becomes chronic. The pain occurs every day, continuously, with varying degrees of intensity.

Tricyclic antidepressants are prescribed for a long course of 2-6 months. They relieve pain and help normalize the psycho-vegetative state of the nervous system.

Amitriptyline 10-100 mg/s is most often prescribed, the dose is increased gradually. The drug relieves pain well, but has many negative side effects and is addictive.

As an alternative, selective serotonin reuptake inhibitors are prescribed: Fluoxetine, Paroxetine, Sertraline. The course of treatment is at least 2 months. These drugs have less toxicity.

In addition to prescribing drug therapy, the doctor will recommend massage, a course of physiotherapy or acupuncture.

Circulatory system

When studying the anatomy of the head, one cannot ignore such a complex but very important topic as the circulatory system. It is she who provides blood circulation to the head, thanks to which a person can live (eat, breathe, drink, communicate, and so on).

The functioning of our head, or rather the brain, requires a lot of energy, which requires a constant flow of blood. It has already been said that even at rest, our brain consumes fifteen percent of the total blood volume and twenty-five percent of the oxygen that we receive when breathing.

Which arteries supply food to our brain? Mainly:

Its outflow from the bones of the skull, muscles, brain, and so on should also occur. This occurs due to the presence of veins:

Arteries

As already mentioned, the vertebral and carotid arteries, which are presented in pairs, supply food to the human head. The carotid artery is the basis of this process. It is divided into 2 branches:

Blood flow to the muscles is carried out by the external and internal carotid arteries. About 30% of the brain's nutrition is provided by the vertebral arteries. Basilar provides work:

The blood supply to the brain varies depending on a person's condition. Mental or psychophysiological overload increases this indicator by 50%.

Symptoms of the lesion

When different centers of the parietal lobe are affected, different sensations and symptoms arise.

The main lesions of the parietal lobe include:

• Semantic aphasia is a defect in simultaneous analysis and speech production. The patient does not understand complex logical and grammatical structures that describe spatial relationships. Examples of questions: A vase on a table or a table on a vase?
• Who is older - grandma's daughter or daughter's grandmother?

The parietal lobe of the brain is located between the frontal, temporal and occipital lobes. It is an area with gray and white matter, striated with grooves and convolutions. It has a set of certain functions that are lost after hemorrhages, injuries, some neuroinfections, and cancer.

Vienna

When considering the anatomy of the human head, it is difficult to ignore a very important topic - the venous structure of this part of the body. Let's start with what venous sinuses are. These are large veins that collect blood from the following parts:

You can also find another name for them, namely, venous collectors, which are located between the sheets of the lining of the brain. Leaving the skull, they pass into the jugular vein, which runs next to the carotid artery. You can also distinguish the external jugular vein, which is slightly smaller and located in the subcutaneous tissue. This is where blood collects from:

Generally speaking, everything listed above is called superficial formations of the head and face.

Main causes of pain

Headache, localized on the left side of the head, is a nonspecific symptom of more than 50 diseases. Painful sensations are associated with irritation of cranial nerves and pain receptors. Intracranial structures, damage to which causes pain in the head area:

1. Blood vessels.
2. The meninges (the area of ​​the walls of the venous sinuses).
3. Cranial nerves.
4. Cervical nerve roots.
5. Soft tissues covering the cranial bones (skin, tendons, muscle tissue).

Of great importance in identifying the reasons why the head hurts on the left side is the nature of the pain, the circumstances and time of occurrence, and the duration of the attacks. According to the nature of the manifestation, a headache localized in the head on the left side can be pulsating, shooting, aching, pressing, dull or sharp.

Osteochondrosis

If the left side of the head hurts in the occipital and parietal zone, this may indicate the development of cervical osteochondrosis, which is caused by degenerative changes in the vertebral discs. Painful sensations are caused by acute or chronic compression (squeezing) of the nerve roots by the bony structures of the spinal column.

Often the pathology correlates with incorrect body position for a long time - sitting in front of a computer monitor or driving a car. Factors that contribute to the development of the disease include: uncomfortable sleeping place, sedentary lifestyle, poor posture, and genetic predisposition. In elderly patients, osteochondrosis often occurs in combination with pathologies such as arthrosis or spondylosis.

Vertebral artery syndrome is a typical sign of cervical osteochondrosis, which is manifested by a severe, throbbing headache, often localized in the lower (occipital) parts of the left or right side of the head. Painful sensations can radiate to the temporal and parietal zones.

The syndrome occurs as a result of compression of the artery, which leads to cessation of blood flow. Additional symptoms that you should pay attention to: dizziness, blurred vision, confusion, tinnitus, short-term fainting. General weakness, increased fatigue, and numbness of the limbs are often observed.

Migraine

If the left side of your head hurts periodically, it may be a migraine. This type of cephalgia occurs with a frequency of 120 cases per 1 thousand people. Migraine cephalgia is characterized by pulsations in one half of the head (right or left). The attack is often accompanied by nausea and increased sensitivity to light and sound stimuli. After the attack, the patient becomes lethargic and drowsy. The duration of paroxysm is 4-72 hours. Provoking factors:

• Lack or excess of sleep.
• Stressful situations.
• Physical fatigue.
• Eating certain foods (fatty foods, nuts, chocolate).

Disturbances in the functioning of the antinociceptive system (impaired production of neurotransmitters, mainly opioid peptides) play a leading role in pathogenesis. Nociceptive substances excite the trigeminal nerve fibers, which causes pain. In response, the perivascular (surrounding vessels) processes of the trigeminal nerve produce vasoactive substances, which leads to rapid expansion of the vascular lumen.

As a result, the permeability of the vascular walls increases, which leads to the release of nociceptive substances (serotonin, prostaglandin, histamine), which enter the vascular bed. Histamine provokes a narrowing of large arteries and arterioles, while simultaneously causing the expansion of small capillaries. Taken together, the described mechanism activates the trigeminovascular system, which consists of sensory fibers that densely innervate the cerebral vessels.

In childhood, migraine attacks are associated with hyperactivity, emotional lability (frequent mood swings), fatigue, attention deficit, and desire for leadership. As boys grow older, paroxysms gradually regress, while in girls they intensify, which correlates with changes in hormonal levels and the appearance of menstruation. Symptoms of abdominal migraine are pale skin, vomiting, diarrhea, throbbing pain in the abdominal area.

Traumatic brain injury

Mechanical damage to bone structures, soft tissues of the head and brain tissue is one of the reasons why the left side of the skull hurts greatly. According to the world classification, post-traumatic cephalgia is considered to be painful sensations in the area of ​​the skull that appear within 14 days from the moment of injury.

Acute forms usually last for 8 weeks, chronic forms - longer than 8 weeks. In the formation of painful sensations, the leading role is played by the state of the central nervous system and the emotional and volitional qualities of the patient. The intensity and duration of cephalgia often do not depend on the severity of the injury.

Muscles

To put it very briefly, all the muscles of our head can be divided into several groups:

You can guess the functions performed by their names. For example, chewing ones make the process of chewing food possible, but facial ones are responsible for human facial expressions, and so on.

It is very important to know that absolutely all muscles, regardless of their main purpose, are involved in speech.
