The endosteum is the membrane that lines the spaces of spongy bone, the marrow cavities, and the haversian canals of compact bone. It is composed mainly of osteoprogenitor cells that contribute to the growth and remodeling of bone and are necessary for bone repair. The osteons consist of concentric lamellae of the bone matrix, surrounding a central canal, called the Haversian canal that contains blood vessels and supply nerves to the bone matrix. The periosteum acts as an anchorage point for blood vessels to enter and leave the bone. RBC formation occurs in the shaft of long bones.
