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 collagen provides flexibility while the minerals provide tensile strength. The skeletal system has five main functions in the body, three of which are external and visible to the naked eye, and two of which are internal. The external functions are: structure, movement and protection.The internal functions are: blood cell production and storage.ave. The skeletal system is divided into two parts, the axial skeleton and appendicular skeleton. The axial skeleton includes the skull, spinal column, ribs and sternum. The appendicular skeleton includes all upper and lower extremities, the shoulder girdle and the pelvic girdle.
