Skeletal muscles vary in their speeds of contraction. Skeletal muscles, which are responsible for posture and movement, are attached to bones and arranged in opposing groups around joints. For example, muscles that bend the elbow (biceps) are countered by muscles that straighten it (triceps). These countering movements are balanced.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be completely autonomous.
Les muscles squelettiques sont reliés au squelette, soit à un os, soit à des tissus conjonctifs tels que des ligaments. Les muscles sont toujours fixés à deux endroits ou plus. Lorsque le muscle se contracte, les sites de fixation se rapprochent ; lorsqu'il se relâche, les sites de fixation s'éloignent. 3. Les muscles tirent sur les os ...

These muscles help to make up the musculoskeletal (say: mus-kyuh-low-SKEL-uh-tul) system — the combination of your muscles and your skeleton, or bones. Together, the skeletal muscles work with your bones to give your body power and strength. In most cases, a skeletal muscle is attached to one end of a bone.
