The musculoskeletal system's primary function is to connect tissues to bones, thus establishing a physical framework to support the body's weight during movement. This system is given commands via interconnected nerves that communicate sensory interpretation, generate musculoskeletal activity and cause muscular contraction.
Components of the system, aside from the skeleton, include cartilage and joint tissues, both of which serve to attach individual bones through flexible organic material. Knee and ankle joints, for example, are made up of bones connected by articular cartilage layered upon each bone's opposite end. Tendons, meanwhile, operate to attach bones to muscle, while ligaments attach bones to one another.
