Osteocyte

Encyclopedia : O : OS : OST : Osteocyte

An osteocyte, a star-shaped cell, is the most abundant cell found in bone. Once osteoblasts become trapped in the matrix they secrete, they become osteocytes. Osteocytes are networked to each other via long processes that occupy tiny canals called canaliculi, which are used for exchange of nutrients and waste. The space that an osteocyte occupies is called a lacuna (Latin for a pit). Their main function involves maintaining the bone tissue. Tracing the path of an osteocyte can be frustrating, if not impossible.

Hydroxyapatite, calcium carbonate and calcium phosphate is deposited around the cell.
