Bones perform five functions in the body: support,protection,movement,mineral storage,and hematopoiesis.In the discussion of body mechanics,two of these functions-support and movement-are most important.In support,bones serve as the framework and contribute to the shape,alignment,and positioning of body parts.In movement,bones together with their joints constitute levers for muscle attachment.As muscles contract and shorten,they pull on bones,producing joint movement.Protection involves encasing the soft tissue organs in a protective cage.Mineral storage helps to strengthen bones but also helps regulate blood levels of certain nutrients.Hematopoiesis is the formation of blood cells.
