A hydraulic skeleton is composed of muscle and fluid.
Cardiac muscle cells, smooth muscle cells, and endothelial cells.
Skeletal muscle cells are much bigger than cardiac muscle cells. Skeletal muscle fibres are up to 100 micrometers in diameter and several centimeters long while cardiac myocytes are about 15 micrometers in diameter and about 100 micrometers long.
Striated muscles are capable of rapid contraction and are particularly associated with voluntary movements of the skeleton.
All muscle
Tendons
Muscle cells work hard and require a lot of energy so they contain many many mitochondria.
mucle in the skeletal system is cammed skeletal mucle which can only be in the skeleton

Muscles move an animal's skeleton by contracting and relaxing. When a muscle contracts, it pulls on the bones to create movement at the joints. Relaxing the muscle allows the skeleton to return to its original position.
