In fully ossified adult bones, the predominant cell types present are osteoblasts and osteocytes. Osteoblasts are responsible for bone formation; they synthesize and secrete the bone matrix, which subsequently gets mineralized to form bone tissue. Once the osteoblasts become trapped in the matrix they produce, they differentiate into osteocytes, which are mature bone cells that maintain the bone tissue and communicate with other bone cells.

Chondrocytes are associated with cartilage, not bone tissue, and are primarily found in the growing regions of bones during childhood and adolescence. They play a critical role in endochondral ossification, where cartilage is replaced by bone, but they do not exist in adult, fully ossified bone.

Dividing bone cells are not a recognized specific type of cell present in mature bones. Mature bone does not have the same level of cellular proliferation seen in the active growth phases of bone development. Instead, the balance of osteoblasts and osteocytes is key.

Haversian canals are not a type of cell, but rather they are microscopic structures that contain blood vessels and nerves, allowing for nutrient delivery and communication within the bone tissue. They play a critical role in bone vascularization and health but do not represent a cell type
