The bone is formed by mature bone
tissue which consists of osteoblasts, osteocytes and osteoclasts. Osteoblasts and osteocytes are found on the surface of bone
Osteoclasts are found deep in the bone. The deposition and resorption of the osteoblasts, osteocytes and osteoclasts
help maintain bone mass, density and structure. Osteoblasts deposit calcium phosphate out to the bone.
