Osteocyte
[Gr. osteon - bone; Gr. kytos - a hollow vessel, modern usage: cyt- denotes a cell] A mature bone cell derived from an osteoblast and located within a lacuna.

osteocyte A bone cell that is characteristic of adult bone, has developed from an osteoblast, and is isolated in a lacuna of the bone substance.
osteon Unit of bone structure; Haversian system.
Bone is first deposited as woven bone, in a disorganized structure with a high proportion of osteocytes in young and in healing injuries. Woven bone is weaker, with a small number of randomly oriented collagen fibers, but forms quickly.
Osteocytes originate from osteoblasts that have migrated into and become trapped and surrounded by bone matrix that they themselves produce. The spaces they occupy are known as lacunae.
Compact bone has a series of Haversian canals around which concentric layers of bone cells (osteocytes) and minerals occur. New bone is formed by the osteocytes.
Other cells, osteoclasts, dissolve bone with acid that they produce, and then osteocytes lay down new bone. This allows the bone to change shape if necessary and it keeps the bone tissue relatively young.
