The musculoskeletal system is made up of bones, muscles, joints, cartilage, ligaments, and tendons. The main functions of the system are to provide support and flexibility, protect vital organs, and facilitate movement.  Here's some information about the structure and function of each component of the musculoskeletal system: Bones: Provide structure and support the body, protect vital organs, and store nutrients and minerals. Bones also help produce blood cells. Joints: Allow for motion and movement, and provide stability. Bones form joints, which act as levers that muscles pull on to... Show more
