Bone: the tissue
This ground bone preparation shows tissue composed entirely of mature, lamellar bone. The lamellae form Haversian systems (osteons) in which they are arranged around a central tube called a Haversian canal. Osteocyte lacunae are flattened and positioned between the lamellae. Also visible are Volkmann’s canals, which are perpendicularly oriented tunnels that connect Haversian canals of adjacent osteons. Both Volkmann’s and Haversian canals contain blood vessels and are lined by endosteum. 400x
