A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. 206 separate bones in the adult, not counting numerous small sesamoid bones. Their unique composition and design allows bones to be relatively hard and strong, while remaining lightweight. The elasticity of collagen improves fracture resistance.
