Now let me talk about some weird cold knowledge:
. The longest tongue recorded in the Guinness World Record is 10.1 cm, and I feel that he has to make a girlfriend with a bigger mouth.
2. The ability to roll the tongue is determined by genes. Do you know?
3. How should the tongue be placed in your mouth? This is quite particular. The one placed at the bottom of the mouth is called the low tongue position, and the one placed at the top of the mouth is called the high tongue position. The low tongue position is not good, which will cause the jaw to narrow and affect the airway space. Some people are used to the tongue against their teeth. When swallowing, the tongue will stretch forward reflexibly, and the teeth are subjected to forward thrust. Over time, the protrusion of the teeth is likely to occur.
4. After sticking out your tongue, you can't breathe quickly with your mouth. If you don't believe it, try it.
5. It is actually difficult to bite the tongue and commit suicide. It is not just about the length that can be extended outside the mouth. It only accounts for two-thirds of the entire tongue, and one-third of it hides in the throat, which is called the root of the tongue.
In fact, the tip of the tongue is covered with capillaries, and there is no such thing as heavy bleeding at all. Moreover, the tongue has a strong ability to heal. Even if you accidentally bite and bleed, it will heal after a while.
As for the lingual artery and lingual vein hiding behind the root of the tongue, although its bleeding is very large and even fatal, it is almost difficult to bite in our daily lives, and the possibility is even zero.
Therefore, it is almost impossible for humans to bite their tongue and commit suicide, let alone worry that they will lose their lives by biting their tongues randomly.
