Skeletal muscle is a kind of muscle, the specific situation is that muscles are usually divided into smooth muscle, cardiac muscle and skeletal muscle depending on their structure. Skeletal muscle is the dynamic part of the motor system, mostly attached to the skeleton, as well as the heart muscle have transverse lines, all belong to the transverse muscle, a few attached to the skin, called the skin muscle, in the human body is extremely widely distributed, there are more than 600, accounting for about 40% of body weight. Through functional exercise, the continuous development of skeletal muscle can be promoted, which can prevent skeletal muscle atrophy, while enhancing strength and power, further protecting adjacent joints and bones, alleviating clinical symptoms, and preventing the occurrence of disease. Therefore, the skeletal muscle is vital to the human body and is an important part of the muscle, which should be protected and strengthened in ordinary life.
