The lamellar tissue between adjacent osteons is called?

• A. Lacunae
• B. Canaliculi
• C. Trabeculae
• D. Interstitial lamellae

Answer: (D)

In compact bone, the basic unit is the osteon, a cylinder with concentric lamellae around a central canal. The lamellar tissue that sits between these adjacent osteons is interstitial lamellae. They are essentially remnants of old osteons that were partially resorbed during remodeling, filling the spaces between newer osteons. Lacunae are the small spaces housing osteocytes, canaliculi are the tiny channels between lacunae, and trabeculae are the lattice-like structures of spongy bone—none of these describe the lamellar tissue between osteons.
