NON-LAMELLAR AND LAMELLAR BONE – 1
Top figure – non-lamellar bone
Osteocytes (highlighted in blue) irregularly distributed throughout the extracellular matrix.
Osteoblasts located on the bone surface are highlighted in yellow.

Bottom figure – lamellar bone
Osteocytes (highlighted in blue) regularly 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 form the endosteum. The outer surface of the bone is covered by a layer of connective tissue, the periosteum.
