Periosteum

a specialized, vascular connective tissue with bone-forming capability that lines all the bones of the body. This periosteal membrane is continuous with the surface of bone except at intra-articular portions of synovial joints, which are covered with synovial membrane or cartilage. The site at which the fibers of tendons or ligaments blend with the periosteum is termed an enthesis. The periosteum may be involved in a number of processes, including inflammation (periostitis). Desmoid tumour, ganglion and osteophytes may also be found in association with the periosteum.
