  1. Yes, in games and movies-this is a convention (well, not really, if you take Tarantino's films, for example, where shots blow half the skull-there are usually no questions here :)).

    In “real life”, the” success ” of a shot depends on both the caliber and the trajectory of the bullet. Actually, 100% death is guaranteed if the shot qualitatively damages the medulla oblongata (medulla oblongata), which manages vital functions: such as breathing, vascular tone, protective reflexes, heart activity, etc.Other parts of the brain, for the most part – not so “mandatory” (although, of course, important) for survival, their functions can be divided between other zones and structures partially or sometimes fully even.

    The “professional control shot” mentioned by Andrey is, in fact, a shot aimed at this area; it is, of course, not in the center of the forehead, but rather opposite the tip of the nose or at the base of the back of the head (thus, if I am not confused, in the PRC they shoot people sentenced to death).

  2. In some patients, this condition develops very slowly and gradually. Giving time and opportunity for the vessels to move apart, brain areas take on the functions of dying ones.

    And when a bullet hits the brain, there is at least an instantaneous violation of blood supply. Without it, the brain is not supplied with oxygen and dies. We lose consciousness when the heart stops in a few seconds.

    Perhaps the destruction of areas of the brain that are responsible just for the same breathing, for example. It's instant death again.

    At the same time, not every brain injury caused by a bullet means instant death. There are many cases when people stay alive. These are usually tangential cortical injuries. Only here it is even impossible to remove the bullet, because, again, getting into the brain is an additional risk and you need to get in quickly and solve a lot of additional issues, such as not introducing infection.

    Let's see how the bullet goes through the apple:

    A channel is formed with terrible destruction. And the skull is much stronger, so if it is not punctured carefully, the bullet will crumple against it and destroy a large area.

  3. The human head can be simply represented as a closed vessel with a liquid. The role of the walls is played by the skull, the role of fluid is played by the brain. OK, the brain is not liquid, rather jelly-like, but of all our organs, one of the most liquid – 80% consists of water.

    The bullet has a certain energy calculated from the formula of physics: the energy of the bullet is equal to the mass of the bullet multiplied by the square of the velocity divided by two. The destructive effect of a bullet depends very much on its speed, rather than on its mass and caliber. The higher the speed of the bullet, the greater the volume of fluid it will displace from the affected organ as it passes through it. The ability of a bullet to deform or fragment when it hits a target also plays a significant role. Thus, rifle bullets will have the greatest striking effect as the fastest-naturally, at relatively short distances.

    Hitting the head in a straight line, the bullet breaks through the wall and skulls and enters the interior at high speed. It produces a fairly extensive destruction of brain tissue, according to the energy that it has. The semi-liquid substance of the brain in a closed volume is very much destroyed by such a blow. If we are talking about pistol bullets with relatively low energy, then these destructions are relatively small and with a successful combination of circumstances, a person can be saved. A rifle bullet, rifle bullet, or buckshot charge has very high energy, can destroy the entire brain and tear the entire skull apart at the seams. In this case, the victim has no chance of survival from the word at all. I once saw a suicide with a hunting rifle – an unpleasant sight…

    Not all injuries and brain injuries are fatal. The greatest danger is caused by damage to the lower parts of the brain responsible for breathing, heart rate and movement. If the bullet hit them, there is a 99.99% chance that the person will either die instantly or die within a few minutes. Professionals shoot not in the forehead, but in the bridge of the nose. There is also a high probability of death if a bullet hits the main arteries inside the head – internal hemorrhage occurs and further brain death occurs. A lot depends on the amount of brain tissue affected – in some situations, a person can be saved, but this is just a formality, he will live with the help of supportive equipment.

    Almost any injury with damage to the brain substance leads to severe consequences-according to the location of the wound and its vastness. A person can lose memory, thinking, speech, go blind, or become deaf. There can be a sharp personal degradation, the character can become simply unbearable. In youth, due to better neuroplasticity and regeneration, you can try to somehow make up for this defect,but you can't do it completely and turn everything back.

    PS Take care of your head, it will still be useful to you.

  4. Here flashed the message that if the respiratory center in the brain is damaged, death is instantaneous, this is absurd! When the breathing apparatus stops, death is extremely painful. I recently got into such a situation, I was well aware that I was suffocating and could not do anything about it, thanks to the surgeon who noticed my condition in time. It was scary and painful.

  5. a) death itself is not instantaneous: from the cessation of blood supply to the brain to its irreversible changes, it takes several years.minutes. At the same time,brain activity does not stop instantly, but gradually fades out.
    b) even damage directly to the brain body-does not cause its instant “shutdown”. The brain consists of different parts that can duplicate the functions of the affected area in certain situations, or simply”turn off”, depriving a person of some functions, but without leading him to the termination of biological existence as such. This is precisely the case in medical practice – when certain parts of the brain are cut out-without the individual ceasing to exist. In non-medical conditions, the chances of survival even with damage to non-critical parts of the brain are minimal-due to infection,sepsis of healthy organs by decomposing affected parts, but still there.
    c)as mentioned above,only the damage to the brain region responsible for primitive reflexive motor functions is critically dangerous and almost irreversible, and only in this case the clinical picture of death will resemble a picture from a movie: I fell like a log and that's it… And then not always-spinal cord damage-from the outside will look exactly the same,but it may not cause death of the affected person at all. In all other cases (and this happens much more often) from the moment of defeat to the moment of cessation of all visible signs of biological existence, some time passes (from nesk.seconds to nesk.minutes), when the body (perhaps reflexively,or maybe because of the residual fading signals of the brain) continues to retain motor abilities: facial expressions are preserved, the body bends, arms and legs make chaotic movements, saliva is released, involuntary defecation occurs, etc… I don't know what this is called in medical circles,but in everyday life-“agony”. In the cinema, these, to put it mildly, unaesthetic scenes are avoided-so the impression of “instant and aesthetically beautiful Death” is created-as in the cinema…..Well, this is a movie-in it you can shoot 15-20 times in a row from a Colt and an explosion from a hand grenade (cotton with a ball of dust and smoke in 1-2 cubic meters).meter) – slightly smaller than a nuclear explosion))))

  6. Not always fatal, but in most cases fatal. There are a lot of criteria: where exactly the bullet hit, distance, caliber, etc. For example, a bullet of the “DUM-DUM” type will not leave the slightest chance of survival, due to the scattering of bullet fragments. In this case, the brain will turn into pate, if it remains in the skull at all. Another thing is the “military” warheads, whose main goal is to disable the enemy at the moment, not necessarily to kill, as long as they do not provide further resistance. But bullets for elimination are arranged differently. Usually blunt-headed, literally, and with a collapsing bullet body when colliding with an obstacle , in this case with the bones of the skull. In this case, the mass of the bullet penetrates the bone and then fragments of the skull and explosive bullet fly, causing brain damage incompatible with life. Again, not all brain damage is fatal. It all depends on how extensive the damage is and in what area exactly. And don't forget about the water hammer, which tends to break everything in its area of operation,( we humans are almost water)), 70% of the water). So combat sharp-nosed bullets leave a person with a lot of chances to survive, melee charges, especially explosive ones, bring the chance to zero. In any case, it's best to never test it in public. There is such a berry as watermelon, very similar to our heads. Well, shoot at it with different types of ammunition, and everything will fall into place. I forgot to add that the American police often use explosive bullets and shotguns to cause as many injuries as possible to a person. For your school….They're really worried.

  7. Because the bullet blows half the skull, the brain shatters, compared the operation when everything is removed carefully and the bullet transmitting its destructive energy to the tissues, the same thing

  8. Because the bullet has a high kinetic energy and hitting the jelly-like substance, similar to our brain, causes a destructive shock wave. The Internet is full of videos of a bullet passing through a ballistic gel. The same thing will happen with the brain. Therefore, the severity of the wound does not depend on what area the bullet hits, but on its mass, size and speed.

  9. In general, there is not everything so simple, in fact, and the problem of hits to the head worries humanity much longer than there are firearms. It is believed that the medieval prohibitions of the crossbow are connected with the fact that a heavy projectile, which hit the forehead with a fairly serious speed, simply broke noble necks. This point is important to remember!

    There is some information that allows us to make correlations between a broken neck from a bullet and mortality from headshots. Because, as mentioned above, it contains the medulla oblongata, which is responsible for basic functions.

    Engineers from various countries in World War I and World War II spent a lot of time, money and personnel trying to make the perfect helmet that would hold a bullet from most small arms. But they consistently came to the conclusion that the bullet, if it does not penetrate the helmet, breaks the soldier's neck. And at some point, either they abandoned the helmets altogether, so as not to create an extra load, or they lightened them to the point that they protected only from accidental fragments. This is me, in fact, to the fact that direct penetration of the skull is not so terrible as other effects.

    And so people after getting hit in the head can live for quite a long time and even fully. I personally knew my grandfather, who in 1944 caught a cherry-sized shard with his forehead, after which he fought for several more months, made a good career by Soviet standards, and died at almost 90 years old.
