A microscopic unit of mature bone composed of layers of osteocytes and bone surrounding a central canal. Also known as Haversian system.



(also haversian system), a system in the bones of vertebrates and man that consists of from five to 20 lamellae arranged concentrically around a haversian canal. It is the structural unit that gives strength to compact bone. Osteons are interspersed with interstitial lamellae. (SeeHAVERSIAN CANALS.)
