The skeletal system consists of 206 bones that provide structure, protect organs, and allow for movement. There are three main types of joints - fibrous, cartilaginous, and synovial. Synovial joints have synovial fluid that lubricates and nourishes the joint, allowing for the greatest range of motion. The skeletal system works with muscles and ligaments to form the musculoskeletal system, which enables movement of the body.
