ANATOMY

Detailed explanation-1: -Volkmann’s canals are any of the small channels in the bone that transmit blood vessels from the periosteum into the bone and that communicate with the haversian canals. The perforating canals provide energy and nourishing elements for osteons .

Detailed explanation-2: -Volk·mann’s canal ˈfō(l)k-mənz-: any of the small channels in bone that transmit blood vessels from the periosteum into the bone and that lie perpendicular to and communicate with the haversian canals.

Detailed explanation-3: -The Haversian canals are straight and long and parallel to the length of femur. The Volkmann’s canals run perpendicular to the Haversian canals, interconnecting the latter with each other and the periosteum, and extending in random directions at various angles.

Detailed explanation-4: -Volkmann canals also contain nutritional vessels arising from the periosteal and endosteal bone surface, which connect with the Haversian vessels within the osteons.

Detailed explanation-5: -Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
