The endosteum (plural endostea) is a thin layer of connective tissue which lines the surface of the bony tissue that forms the medullary cavity of long bones.^[1] This endosteal surface is usually resorbed during long periods of malnutrition resulting in less cortical thickness. The outer surface of a bone is lined by a thin layer of connective tissue that is very similar in morphology and function to endosteum. It is called the periosteum, or the periosteal surface.
