GENERAL HISTOLOGY

Detailed explanation-1: -Haversian canals( are a series of microscopic tubes in the outermost region of bone called cortical bone that allow blood vessels and nerves to travel through them. Each haversian canal generally contains one or two capillaries and nerve fibres. The channels are formed by concentric layers called lamellae.

Detailed explanation-2: -A central Haversian canal penetrates the osteon and serves as a passage for blood cells, lymph vessels, and nerves.

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: -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.

Detailed explanation-5: -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.
