The function of the muscles, what is the function of the muscles

1. Songkai muscles are mainly composed of muscle tissue. Muscle cells are elongated and fibrous in shape, so muscle cells are often called myofibers. In TCM theory, muscle refers to the general term for the body's muscle tissue and subcutaneous adipose tissue.

The spleen is the main muscle, and the nutrition of the muscles is obtained from the spleen's transportation and water valley. Muscle: Anatomical name.

Therefore, whether the muscles are full or not is closely related to the prosperity and decline of the spleen. "Su Wen Pingren Meteorological Theory": "The viscera is really wet in the spleen, and the spleen hides the qi of the muscles."

Su Wen and the Theory of Impotence: "The muscles of the spleen and body." ”

2. Muscle function: muscle contraction and traction of bones to produce joint movement, its effect is like a lever device, there are three basic forms: balance lever movement, the fulcrum is between the focus and force points, such as the head and head down movement carried out by the atlanto-occipital joint; Labor-saving lever movements, where the focus is between the fulcrum and the force point, such as the movement of the ankle joint when starting to raise the heel; The speed is the movement of the lever, and the point of force is located between the focus and the fulcrum, such as the movement of the elbow joint when lifting a heavy object.

Working muscles are the muscles that we use to maintain posture and support the body in our work and daily life, and their functions include:

1.Maintain body posture: Working muscles are mainly used to support and maintain the posture of the body, such as maintaining balance and stability of the body while standing, walking, sitting, and standing.

2.Participation in movements: In different work and daily activities, the working muscles will also be involved in the execution and control of movements, such as reaching forward, bending knees and squatting.

3.Protects internal organs: Many working muscles are located in the abdomen and pelvis, and their contractions can help protect the organs in the abdomen and pelvis.

4.Metabolism: The contraction of the working muscles also produces heat and consumes energy, which has an impact on the body's metabolism.

Therefore, maintaining good working muscle condition is essential for good health and correct posture, and proper exercise and rest can help us to improve working muscle fatigue and prevent muscle damage.

The muscle fiber tension lasts for a short time, the contraction laughs and relaxes continuously, and often changes the tension angle, the direction and the position of the bone lever, this kind of work is called dynamic work, and dynamic work is divided into two kinds: centripetal work (restraint work) and centrifugal work (concession work).

1) Centripetal work.

Muscle contraction overcomes resistance, muscle strength is greater than resistance, and the work of making the movement link move in the direction of muscle tension is called centripetal work. For example, the deltoid and supraspinatus muscles abduct the shoulder joint by nature, which is centripetal work.

2) Centrifugal work.

The muscles are gradually elongated under the action of resistance, and the resistance is greater than the muscle strength, so that the movement link moves in the opposite direction of the muscle tension is called eccentric work. For example, in gymnastics, the knee flexion cushion, the quadriceps muscles are wide and wideQualitative is centrifugal work.

Muscle is a very important tissue in the human body, everyone's physical activity is inseparable from the contraction force of muscles, only can maintain the basic life of the human body, and also has a very important role in our health. Today, I will tell you about the specific role of muscles in the human body?

1. Muscles can prevent joint pain. The skeletal junction of the human body is the joint muscle, which can help the joint stabilize, as long as the muscles around the joint are trained, it can play a role in strengthening the joint, and can prevent various bone and joint pain. Muscles can help the joints play a supporting role, if the muscles decline, the important strength of their body will not be enough, the joints will become very unstable, you will feel joint pain, many elderly people or people who sit still for a long time will have back pain, it is because of their long-term lack of exercise resulting in muscle atrophy and decreased strength.

2. Get thinner. Many ** people envy others who eat a lot of things and do not gain weight, but in fact, this is determined according to the individual's physique, each person has a different proportion of muscle on the body, the more muscle content of the same weight, the more energy consumed, and it is not easy to get fat under the same diet, this is the so-called easy to lose weight, and the volume of muscle and fat fat of the same weight is much larger than that of muscle, so in the case of equal weight, people with high muscle content also look slimmer.

3. Muscles protect bone health. Our bones are also surrounded by muscles, only after the muscles grow, in case of accidents, the bones can be better protected, increase the resistance of muscle strength will increase the bone density of young people, so that the elderly can delay bone loss, which is conducive to bone health and prevention of osteoporosis.

If the muscles in the human body are not strong enough, it is easy to cause muscle injury. Regular muscle exercise can also slow down aging. For obese people, regular muscle exercise can also make them thinner.

If the muscles in the neck or back are not strong enough, it can lead to cervical spondylosis and lumbar spine disease.

The functional connection of the muscles of the body and the role of execution, without which the movement cannot be completed through the nerves. The muscles protect the bones and reduce the cushioning brought to the bones by resisting hits, bumps, bumps, and bumps.

Muscles are divided into skeletal muscles, smooth muscles, and cardiac muscles. Skeletal muscles are attached to bones, and all actions of the human body are done through skeletal muscle contraction, without which there is no production of movements.

The heart muscle is the heart, which is an important organ of the human body and brings power to people's blood transportation. Smooth muscles are only muscles of the gastrointestinal tract.

Muscles play a vital role in the human body because they reduce cushioning of bones and joints, reduce wear and tear on joints, and improve the ability of limbs to move.

It has a contraction effect, can help people to complete a variety of movements, can protect internal organs when falling, and I have learned that there are many muscles in the human body, which can achieve the effect of shaping and make people look healthier.

It can improve resistance, it can also protect the joints, it can also reduce the wear and tear of the joints, it can promote the ability to move, and it can also avoid injuries. The muscles have a strong executive ability, which is closely related to the body's functions, and will not lead to injuries to the human body, and the muscles need to be trained to balance the body's ability and improve the metabolic capacity.
