Plate 3.49: Bone

Human, ground bone, 162 x.

Haversian canals: These are abundant and characteristic of compact bone. Their course follows the main axis of long bone. They conduct blood vessels, lymphatics, and nerves throughout the bone. They branch and anastomose and become continuous with Volkmann's canals. Haversian* canals surrounded by concentric lamellae of compact bone form the Haversian system.

Volkmann's canals: These are cross connections between Haversian canals. They pierce the lamellae of two Haversian systems. They contain blood vessels, lymphatics, and nerves and supply the interstitial lamellae.

Interstitial lamellae: A set of bone lamellae that fill the spaces between Haversian systems. They vary in shape and orientation.

*Havers was a seventeenth-century English anatomist and Volkmann was a nineteenth-century German physiologist.
