Periosteum

The periosteum is a membrane that covers the outer surface of all bones,[1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.) Endosteum lines the inner surface of the medullary cavity of all long bones.[2]

Etymology[edit]

The word periosteum is derived from the Greek peri-, meaning "surrounding", and -osteon, meaning "bone". The peri refers to the fact that the periosteum is the outermost layer of long bones, surrounding other inner layers.[6]
