The function of skeletal muscle is to contract to move parts of the body closer to the bone that the muscle is attached to. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other.

Skeletal muscles have an abundant supply of blood vessels and nerves. This is directly related to the primary function of skeletal muscle, contraction. Before a skeletal muscle fiber can contract, it has to receive an impulse from a nerve cell.

Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm.

Skeletal muscle: This type of muscle creates movement in the body. There are more than 600 skeletal muscles, and they makes up about 40 percent of a person's body weight.

Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other.

Four characteristics define skeletal muscle tissue cells: they are voluntary, striated, not branched, and multinucleated. Skeletal muscle tissue is the only muscle tissue under the direct conscious control of the cerebral cortex of the brain, giving it the designation of being voluntary muscle.

The Four Types of Tissues Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart.

The skeletal system includes four basic components, although some sources include a fifth, the joints. The four are the bones, which make up most of the mass of the skeletal system; cartilage, which acts mainly as padding; ligaments, which usually connect bones to bones; and tendons, which join muscles to bones.

The Human Body Has Over 600 Skeletal Muscles That Move Bones and Other Structures. Skeletal muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system. Skeletal muscle tissue is composed of long cells called muscle fibers that have a striated appearance.
