The microscopic, laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone, haversian systems consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacune are present at the junctions of the bony layers of the haversian systems. |
