Osteon matching

Endosteum

CT membrane covering internal bone surfaces

Osteocytes

Mature osteoblasts that reside in lacunae

Trabeculae

Tiny bone spicules lined with endosteum that make up spongy bone

Periosteum

dense irregular CT that surrounds a bone; houses bone forming cells, bone destroying cells, and numerous blood vessels

osteon

densely packed subunits of compact bone

Central canal

found in the center of each osteon; contains blood vessels and nerves

perforating canal

lie perpendicular to the osteon and carry blood vessels into the bone from the periosteum

Concentric lamellae

rings of bone matrix

Lacunae

small cavities containing osteocytes located between concentric lamellae in which osteocytes reside

Canilculi

tiny canals that join neighboring lacunae and their osteocytes
