How do human muscles move?

The human body is a very magical system. Any system in the human body is closely connected, especially the human muscles. In addition to being developed through exercise, human muscles actually exist inside our bodies. Skeletal muscle is the more important muscle. So what does human muscle do when it exercises? Next, let me explain it using skeletal muscle as an example.

Muscles - the engine of human movement. The muscles mentioned here mainly refer to skeletal muscles. Skeletal muscles and bones together constitute the human body's organs of movement. Skeletal muscle is the "engine" of human movement, providing power for human movement. There are more than 600 skeletal muscles in the human body, accounting for 40% of body weight. The two ends of skeletal muscles are white tendons, which are fixed to different parts of the bones. The thicker middle part of skeletal muscle is called muscle, which is the main part of muscle contraction.

Skeletal muscle is composed of many muscle fibers, among which are many blood vessels that nourish the muscles and nerves that control the muscles. All activities of our body, big or small, are completed by the contraction and pulling of the corresponding bones by the "engine" called muscles. Therefore, skeletal muscle is the engine of human movement. Physical exercise can promote muscle development and enhance muscle strength. This is because only some muscles are involved in movements in daily life, but during physical exercise, all muscles in the body are involved. The capillary network in the muscles is mostly open to supply the muscles with more nutrients, making the muscles gradually become thicker and stronger.

The muscles of the human body are very magical. They support our body to maintain normal movement. In addition to some muscles that can be seen with the naked eye, there are also muscles in the human body, such as skeletal muscles, which play a very important role in the human body. Therefore, we must protect these muscles in our daily lives, and also pay attention to warming up before exercise.
