Microscopic Anatomy of Bone: Compact and Spongy Bone

Perforating (Volkmann’s) canals
In compact bone
At right angles to the central canal
Connects blood vessels and nerves of the periosteum and central canal

Lacunae
In compact bone
small cavities that contain osteocytes

Canaliculi
In compact bone
hairlike canals that connect lacunae to each other and the central canal

Spongy Bone
Trabeculae
Align along lines of stress
No osteons
Contain irregularly arranged lamellae, osteocytes, and canaliculi
Capillaries in endosteum supply nutrients
