WebThe terms 'Haversian system' or 'osteon' refer to the basic cylindrical-shaped structural unit of a compact bone, which in turn forms a substantial part of the structure of the long bones of the human body. The osteons are closely packed, with osteocytes lined up in concentric rings. This imparts a hard and dense texture to the compact bones. WebAn osteon is the cylindrical structure with bone. An osteon is also called a Haversian system. The mature bone cell is called an osteocyte. It sits in a space, called a lacuna. An osteoblast is an immature bone cell. The osteoblast is the bone forming cell. Osteoid is unmineralized bone matrix. 3.
