In film and television dramas, we often see such a scene: when the heroine is dealing with the bad guy face to face, the actor suddenly appears behind the bad guy and slashes his neck with his bare hands, and the bad guy faints immediately. In fact, in real life, you will really get dizzy as soon as you chop. Sometimes, if the force of the split is not well managed, it will cause sudden death.
In film and television dramas, we often see such a scene: when the heroine is dealing with the bad guy face to face, the actor suddenly appears behind the bad guy and slashes his neck with his bare hands, and the bad guy faints immediately. So, the neck is really so fragile, it will dizzy when it is chopped?
Does your neck really faint when you chop?
In fact, it’s true that you get dizzy when you chop your neck with your bare hands. This is because there are some vital parts on the neck: carotid artery, trachea, etc. Especially the carotid artery, which is distributed on both sides of the neck. There is a carotid sinus at the branch of the carotid artery. The blood vessel wall in this part is very thin, the lumen is enlarged, and it is very fragile.
In medicine, the carotid sinus is often referred to as a protective device for the human body. This is because it has a baroreceptive nerve ending device, which is the carotid sinus baroreceptor. As long as your blood pressure changes slightly, it can not only be clearly felt, but it can also regulate your blood pressure-when your blood pressure rises, it will drop one for you, and when your blood pressure drop, it will give you one rise.
At this time, if someone suddenly strikes the side of your neck, it will give the illusion of the carotid sinus, thinking that the blood pressure has risen, it will instinctively lower the blood pressure. If you work harder, your blood pressure will drop sharply. A sudden drop in blood pressure prevents blood from reaching the brain, which causes cerebral ischemia. In this way, the heart cannot work properly. The heart rate drops and fainting is inevitable. Moreover, if the force of the split is not handled well, it will cause sudden death.
These seem to be correct, but they are actually wrong
In addition to splitting the neck with bare hands, which can make people wonder, there are many scenes in film and television dramas that make people know whether they are true or false.
For example, when an actor expresses a heart attack, he often falls to the ground suddenly with his hands on his chest, and his expression is extremely painful. However, the reality is not the case. It is understood that treatment within 1 hour after a heart attack is most effective. However, people usually call an ambulance one and a half hours after a heart attack because they have been waiting for the pain to disappear naturally. In fact, the symptoms of a heart attack are usually milder, not as severe as they appear in movies and TV shows. Because of this, it will cause viewers to ignore the symptoms of heart attack and affect treatment.
In addition, in film and television dramas, suicide by swallowing a large amount of sleeping pills is regarded as a very beautiful way of death. However, swallowing sleeping pills is actually the most painful and least dignified way of suicide. Because, within 48 hours after swallowing sleeping pills, not only is it impossible to fall asleep, but also symptoms such as stomach cramps, abdominal pain, foaming at the mouth, etc., in summary, the internal organs are like overwhelming. Moreover, the commonly used sleeping pills are not so easy to kill. Perhaps swallowing hundreds of sleeping pills in one breath will not only kill you, but also suffer painful torture.
These look wrong, but they are actually correct
In the film and television series, there are still some scenes that seem impossible, but they are actually true. For example, in a domestic drama, every time a surgeon enters the operating room, he wears a dark colored surgical cap, which looks very fashionable. In the foreign film “Grey the Intern”, three heavyweight experts enter the operating room wearing surgical caps of different colors. Are they acting handsome?
In fact, this is real. It is understood that the caps and clothes in the operating room in China are uniformly disinfected every day after being worn. In foreign countries, many surgeons can wear their own special surgical caps. Therefore, when American doctors perform operations on patients in hospitals, they wear colorful surgical caps. They believe that wearing flower hats can not only create a relaxed working environment, but also relieve the patient’s nervousness.
