ANATOMY

Detailed explanation-1: -Haversian canals (sometimes canals of Havers) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves to travel through them to supply the osteocytes. Diagram of compact bone from a transverse section of a typical long bone’s cortex.

Detailed explanation-2: -Compact Bone The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix.

Detailed explanation-3: -Haversian canals are a series of tubes around narrow channels formed by lamellae. The Haversian canals surround blood vessels and nerve fibers throughout the bone and communicate with osteocytes. The canals and the surrounding lamellae are called a Haversian system (or an osteon).

Detailed explanation-4: -Haversian canals typically run parallel to the surface and along the long axis of the bone and generally contain one or two capillaries and nerve fibers. Volkmann’s canals are channels that assist with blood and nerve supply from the periosteum to the Haversian canal.

Detailed explanation-5: -Haversian canal in the bone of mammals are connected by small blood vessel canal called Volkmann’s canal. 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.
