What organs are included in the musculoskeletal system?

The main components of the musculoskeletal system of humans and vertebrates are bones and muscles. Bones help the body to maintain its shape and position, protect internal organs from displacement and damage. Muscles, controlled by nerve impulses emanating from the brain, make it possible to perform various movements necessary for the vital activity of the organism, and to move in space. Bones connect to muscles and to each other through joints and ligaments, which are made up of cartilage and connective tissue.
