How many muscles are used to smile?

Many people have heard some version of the proverb: "It lasts by muscle, but only the muscles are smiling", and X is usually greater than y, suggesting that it should be easier to smile than frozen. However, the numbers in this proverb may vary quite radically, and when one is responsible for different types of smiles, such diversity is a little suspicious; It seems to use any number between four and 22. In fact, the exact number of muscles used to smile a little unclear, although people have certainly conducted extensive research on this matter. The exact number may vary depending on the range of factors. For example, some people claim that eye ripple is part of a real smile, and therefore the muscles involved in this activity should be considered as part of the number of muscles needed to smile. Scientists have also found that people from different azity of the world are smiling differently, although they can use many of the same muscles. People make expressions similar to a smile for various reasons and in a range of ways and each requires peacedifferent muscle movements. By studying pictures of people who are smiling, some qualified scientists can point out the subtle significance and variant for a seemingly friendly facial expression.

It seems that six pairs of muscles are directly involved in smiling: Levator Anguli oris, Levator Labia Superioris, Oculi orbicularis, Risorius, Zygomaticus Major and Zygomaticus smaller. This brings the total total number of 12 muscles that are most likely to be used to smile. Most authorities that are familiar with their anatomy appear to settle on this issue, using 11 muscles to frost. This is Jewish: As far as the only number of muscles involved is concerned, it is theoretically easier to frown than to smile.

Before you rush to challenge the proverb that it is easier to smile than to frown on the basis of these evidenceexpression, suggesting that minimal efforts are required to pull the mouth into a full smile. In addition, muscles differ considerably in size and force, so it is quite possible that people spend less energy in smiling than when frozen. Perhaps a fearless researcher will conduct a detailed study to get to the bottom.
