Answer: D - The function of the musculoskeletal system is to give the body shape, protect internal organs, and to provide for movement. With the skeletal structure forming an upright frame, the muscles attached to the bones provide for movement through contraction and relaxation. The skeleton not only provides the frame, but - in the case of the cranium, rib cage, and pelvis - protection of internal organs. The muscles not only move the body around but also, via connective tissue, unify the skeleton and hold the joints in place.
