Hi friends steemit

The human body is truly amazing. For each of us, it represents the most we know in this world, yet many of us do not know many things about its body: its features, functions, experiences, and features

Today I present to you in this article some facts about an important part of the human face is the "chin", it is the chin with the simplicity that appears on it, that bone bulge at the bottom of your face, it is part of the integral part of the human body, and is surrounded by a kind of mystery that has always left Researchers are at a loss.

Here are facts supported by science about the chin:

1. Scientists and researchers have not yet agreed on the purpose and purpose of the chin:

According to Faisal Tawab, a physician in Orlando, Florida, the most interesting thing about the chin is that there is no clear and convincing answer to what is already there, and why we have a chin in the first place. "Some theories The most famous search for why the chin has the following is: helping us speak, or protecting the jaw from the pressure of the chewing process, or as a way to determine the attractiveness of the other party when looking for a partner, or the sum of the three previous reasons together. " The real purpose of having a chin is on the table, and there is a lot of criticism Current theories that dealt with the subject. "

2. It may help relieve the pressure of the jaw:

The chin may have evolved to protect the jaw from the extraordinary pressure caused by the restructuring of our mouths to enable us to speak, according to a 2007 study published in Medical Hypotheses.

Your chin may help you to tolerate some of the muscle mass pressure that is responsible for chewing and talking (which is why you want to have a strong chin).

3. Chin is very essential for chewing:

"Many muscles are placed in the chin and form part of the occlusal plane," said Francisco Gargano, a cosmetic surgeon licensed by the United States Medical Board at the Plastic Surgery Center in New Jersey. Which is the distance between your teeth when your mouth is closed. "

Many studies support this theory, suggesting that the chin "helps to support the jaw against certain mechanical stresses," including the chewing mechanism, which generates a great deal of strength.

4. Chin may have provided much help to our ancestors during their selection of partners:

According to a recent study, the chin helped our ancestors find, find, and choose partners. "Men tend to have a long chin with a square look and a flat base at the bottom, while females tend to be narrower and more rounded," Gargano said. "

A study conducted in 2010, published in the American Journal of Physical Anthropology, suggests that if there was no relationship to sexual attractiveness, there would be no difference in the structure and shape of the chin in both men and women, because there simply are no functional differences Eat both male and female and speak the same way

5. Humans are the only animals that have our taste:

While humans may share certain things with other animals, the chin is not one of those things; it is the exception here. "Elephants are the only other beings without humans who have a part of the body resembling the chin," says Tawab. Chin "elephants are formed by lack of lower teeth, and have a large lower lip. In fact, it is not a bone bump as we humans are, which is our "real" taste and a unique feature of other beings.

The human chin is a branching classification that characterizes human beings alone. Tawab explains that this is an advantage or a physical member. The first forms of a "class" (a group of organisms that share a common ancestor) do not.

In short, the chin is also a sign of the development of the human race, and one of the physiological characteristics that distinguish us from others.

6. Are your chances of attracting the other party stronger if you have Chin Cleft?

"Historically, many cultures have given special meaning because one is born with a cleft chin, and that usually involves luck in terms of love and relationships," says Tawab. "The reality is not the same. Chinomas, as they are called, occur as a result of incomplete fusion of the two prenatal jaw bones. There are also many forms of cracks and cracks: vertical, Y-shaped, and menstrual.

7. Chin may be where the "stop" development simply:

According to Nathan Holton, an anthropologist at the University of Iowa in the United States, the chin has nothing to do with carrying any pressure or attracting a partner for mating, which suggests that the Hummus - Of humans, nandertal, and some of their relatives as well - and homosabians in particular, have simply developed smaller faces.

"The lower jaw is the last part of the body that stops growing, making it more prominent compared to other parts of the face," Holton said. "The chin is the secondary result of our faces getting smaller."
