Skeletal muscles move the body. Skeletal muscle contractions pull on tendons, which are attached to bones. If contraction of the muscle causes the muscle to shorten, the bone and, thus, the body part will move. For example, the biceps brachii is attached to the shoulder and the forearm bones.keletal muscles serve a variety of functions including support and movement and homeostasis. Skeletal muscle contraction can result in muscle shortening and thus movement of the bone to which it is attached.
Three kinds of freely movable joints play a big part in voluntary movement: Hinge joints allow movement in one direction, as seen in the knees and elbows. Pivot joints allow a rotating or twisting motion, like that of the head moving from side to side. Ball-and-socket joints allow the greatest freedom of movement. The hips and shoulders have this type of joint, in which the round end of a long bone fits into the hollow of another bone.
