Bone matrix
This longitudinal view of compact, lamellar bone shows numerous, vertically-oriented Haversian canals and their interconnecting Volkmann’s canals. Haversian systems are oriented parallel to the long axis of the diaphysis; Volkmann’s canals are oriented mostly in a transverse plane. Ground compact bone, 200x
