The small cavities that house osteocytes are called?

• A. Canaliculi
• B. Lacunae
• C. Lamellae
• D. Volkmann's canal

Answer: (B)

The small cavities where osteocytes live are lacunae. In mature bone, osteocytes sit in these tiny spaces within the mineralized matrix, with each lacuna housing one cell. The cells extend processes through narrow channels called canaliculi, linking lacunae to each other and to blood vessels, which enables nutrient and signal exchange. Lamellae are the concentric layers of bone matrix around the central canal, and Volkmann’s canals are channels that connect different osteons; they don’t house osteocytes. So lacunae are the correct term.
