IN WHAT WAY MUSCLES WORKS?

Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands or even  tens of thousands, of small fibbers make up each muscle. There are more than 600 muscles in the human body. Most muscles are use to move the body parts. The muscles consist of action and myosin. One muscles tightens becomes shorter, pulling the bone after it, If it relaxes, other muscle tightens, the bone moves back. Muscles cannot push they can only pull.
