The human musculoskeletal system (also known as the locomotor system, and previously the activity system[1]) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together.

The skeletal system provides structural support for the entire body.unctions of the Skeletal System The skeletal system has five primary functions: support, storage of minerals and lipids, blood cell production, protection and leverage.
