Decent Essays
There are two types of bone tissue: compact and spongy. The names imply that the two types differ from each other in many ways. There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.
Compact bone consists of closely packed osteons or haversian system. The osteon consists of a central canal called the haversian canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells are located in spaces called lacunae. Small channels radiate from the lacunae to the haversian canal to provide passageways through
