Bottom figure – lamellar bone
Osteocytes (highlighted in dark blue) arranged in layers between bone lamellae.
Osteoblasts placed on the bone surface highlighted in yellow. The layer of osteoblasts that cover the inside (upper) surface of the bone is the endosteum. The outer surface of the bone is covered by a layer of connective tissue, the periosteum.
