What is the mouth used for? What else is the use of the mouth What is the role of the mouth

The human mouth is used to eat and speak.

The first function of the mouth is to eat, or more precisely, to eat. Just like Qian Zhongshu.

Said: "Eating a particular meal is actually eating vegetables." So the purpose of our meals is to distinguish tastes rather than satisfy hunger, but people still disguise enjoyment as need, and do not talk about eating, but only about eating.

The second function of the mouth is to speak, and some people say that speaking is an art, and it is not false at all. If the above is said to be a disguise, it is a serenade.

Then the choice of words and sentences in interacting with people is a huge symphony.

Every note has been scrutinized.

Animal's mouth:

1. Mosquitoes have stinging and sucking mouthparts, their lower lip is extended into a beak, and the upper and lower jaws are specialized into needle-shaped, which is suitable for piercing into animal and plant tissues and absorbing blood and cell fluid.

2. The unique licking and sucking mouthparts of flies, the upper and lower jaws are degenerate, and the mouthparts are specialized from the lower lip, which is particularly developed, like a mushroom head.

There are two round lip flaps on the left and right sides of the lower lip end, and when feeding, the lip flaps are flattened into a disc shape and attached to the food.

3. The distinctive feature of butterfly mouthparts is that there is a beak that can curl and stretch, called siphon mouthparts, and its beak cannot penetrate the tissue, but can only absorb the juice of nectar.

After all, people live with a mouth You must know how to communicate with others, how to be kind to others, learn the charm of speaking, and remember that people who can speak can truly stand invincible. Come on! The mouth can be used for kissing, eating, and breathing.

The mouth is for kissing, not for quarreling.

It's up to you, you can do whatever you want.

A mouthful of eloquence.

Cherry mouth, small mouth, dexterous mouth, watery mouth.

I'm afraid the busiest thing in the human body is the mouth. Whether you bite, eat, swallow, suck, breathe, talk, or sing, you can't leave your mouth for a moment. There is also a mouth in expressing feelings, you might as well try, control the corners of your mouth when laughing, can you laugh?

The human mouth is expressive. The 4 basic ways of mouth muscle movement – opening and closing, forward and backward, up and down, and tightening and relaxing – make up a kaleidoscopic range of mouth expressions. The most important muscles in the mouth are the strong and powerful ring muscles around the lips.

When the annular muscles contract, the mouth closes. If the superficial muscles are more strained, the mouth will pout; If the inner muscles are more forceful, the lips will press against the teeth, forming a tense phase that will be beaten. The other mouth muscles move with the annular muscles, trying to stretch the mouth in all directions.

When the levator muscle lifts the upper lip, it shows a sad or contemptuous expression; The cheek muscles pull the corners of the mouth back and upwards to show a smile; The deltoid muscles of the mouth pull the corners of the mouth downward, which is a sentimental expression; The descending muscles pull the lower lip down, showing disdain or mockery; **The levator muscle elevates the lower palate while bringing the lower lip forward for a defiant look; The platysma muscle, located in the neck, can pull the mouth down or from side to side in response to the tense posture of the neck, which is the case when a person is in pain, frightened, or angry.

There are two types of cheerful expressions: open and closed. The lips are raised back and upwards without opening them, forming a silent smile; A grin is a smile that shows teeth; The mouth is open, and the lips form an arc upwards at both ends, which is a hearty laugh.

When angry, the corners of the mouth are forward, as if to attack; When he is afraid, the corners of his mouth are retracted, as if he is about to escape. The same two expressions, anger and fear, vocal or silent, the shape of the lips varies greatly, while the changes in the corners of the mouth are the same as above. When anger is silent, the lips are pursed tightly and the corners of the mouth are forward; When he roars angrily, his mouth opens wide, revealing two rows of teeth, and the corners of his mouth are still forward, forming a square hole; Silent fear, lips tense contraction, revealing a horizontal crack, the corners of the mouth desperately shrinking back; When he screams for fear of screaming, his mouth opens wide and the corners of his mouth are still shrunk behind his back.

In addition, the mouth can also be used in conjunction with some gestures to express feelings and wishes.

1. Eating, more precisely, eating vegetables.

2. Speak. Speaking is an art, and the choice of words and sentences in interacting with others is a symphony of huge manuscripts, and every note must be scrutinized repeatedly.

3. The judgment is the key to return to the family non. Those who judge right and wrong have a clear position, a strong view of right and wrong, high transparency, weak political sensitivity, and a real talent in their mouths.

4. Tell right and wrong. Those who tell right and wrong are rich in associations, taken out of context, have strong incitement, strong desire for interests, and the talents in their mouths are also very good in the world.
