Haversian canal (ha-ver-si-ăn) n. any one of the small canals that ramify throughout compact bone. Haversian systems are joined to each other by bone material. The Haversian canal is really important because it houses the nerves in the blood vessels and the canaliculi that reach out from that Haversian canal into the osteocytes away from them to bring them nutrients and remove waste. These canals are connected to each other by Volkmann's canals, which are transverse vessels that run perpendicular to the long axis. Near the surface of the compact bone, the lamellae are arranged parallel to the surface; these are called circumferential lamellae. These canals surround blood vessels and nerve cells throughout bones and facilitate communication within bone cells. A Haversian system, also known as an osteon, is a series of concentric circles, called lamellae, found in the compact bone of humans. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Also known as Haversian Canals. A haversian canal is a central canal within the haversian system — a network of canals inside compact bone. This produces several concentric layers of lamellae around a central canal, forming an osteon. Haversian canals allow blood vessels and some nerves to … adj., adj lamel´lar. The currently accepted model of compact bone organization is that of a system of longitudinal canals (Haversian canals) connected by transverse connections (Volkmann’s canals); the blood flow supporting the osteocytes runs in this system of canals [].During bone development, the system of Haversian canals and the related vessel network are created by cutting … (anatomy) The system of osteons in compact bone. Microscopic structure of bone - the Haversian system. Haversian System Structure Diagram and Function. The endosteum also lines each central canal, allowing osteons to be removed, remodeled and rebuilt over … Haversian canals occur in the center of compact bone and contain blood vessels, connective tissues, nerve fibers and lymphatic vessels. The integration of structure and function for tissue engineering scaffolds is of great importance in mimicking native bone tissue. Definition of haversian canal in the Definitions.net dictionary.

They are named after the English anatomist Clopton Havers (1657–1702). Haversian systems are joined to each other by bone material. Variables included in this study were cortical thickness, bone mineral content, cortical bone density, summed Haversian canal area, Haversian canal number, and mean Haversian canal area. As it was already mentioned, the endosteum is located within the medullary canal, in the spongy part of the bone, the haversian canals and inside the cortical walls of the compact bones. Cartilage. Haversian canals typically run … 93 Haversian canal View Virtual EM Slide Note the "inactive" appearance of endosteal cells. Some, mostly older, compact bone is remodelled to form these Haversian systems (or osteons).The osteocytes sit in their lacunae in concentric rings around a central Haversian canal (which runs longitudinally).The osteocytes are arranged in concentric rings of bone matrix called lamellae (little plates), and their processes run in interconnecting canaliculi. Small blood vessels that are present in the central canal perform the function of supplying blood to the osteocytes. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann’s canals, to extend to the periosteum and endosteum. See also bone. [ C.
