The musculoskeletal system is an organ system that gives animals the ability to move to more favorable conditions by using the muscles and skeletal system to engage in locomotion. Bones also serve a role as support and to protect internal organs and in many organisms to store fat and minerals and produce blood cells.

The human musculoskeletal system consists of the human skeleton, made by bones attached to other bones with joints, and skeletal muscle attached to the skeleton by tendons.
