Muscles are made up of protein filaments, namely actin and myosin. The muscle is divided into three sections: striated skeletal muscle, which is a muscle consisting of a bundle of thin fibers, such as the muscles of the head, trunk, and limbs. It allows movement and is called voluntary muscles. Smooth muscle, which consists of cells or rectangular fibers. It is not connected to the skeleton, such as striated muscles, and it surrounds hollow organs. Such as the intestines, trachea, and blood vessels, and it is called involuntary muscles, and the heart muscle. It is also an involuntary muscle, but it is closer in structure to the skeletal muscle, and it is found only in the heart.

The muscle consists of a large number of bundles containing long, thin muscle fibers. When the fibers are in their normal position, i.e. flat, the muscle is flat. When the muscle fibers contract, the muscle contracts and thus decreases in length, and the muscle usually connects to two bones. When the muscle relaxes, nothing happens in them, but as soon as it contracts, the two bones move.
