Snake

The muscular system of the snake is made up of strong muscles throughout its full length. The snake's vertebrae are shaped such that muscles can be attached along the length of them. Snakes are able to move without limbs due to the strength of their muscular system, which causes movement by creating lateral pulses, waving left and right.

The human muscle system, the muscles of the human body that work the skeletal system, that are under voluntary control, and that are concerned with movement, posture, and balance.
