WebThe secondary osteons, or Haversian systems, are roughly cylindrical structures with a central canal. The central canals may branch or merge and are often coaligned in long bones with the prevailing direction being along the bone axis. Historically the longitudinal Haversian canals (HCs) were distinguished from the transverse Volkmann’s canals. WebSo let's talk more about this haversian system. So each of these osteons looks like of like a cylinder and it has multiple concentric layers of bone, or sheets really, that wrap around each other to form this osteon. Each of these layers is called a lamellae. In the center of these layers is a canal called the haversian canal, or central canal.
