What are the small cavities that house osteocytes called?

• A. Canaliculi
• B. Lacunae
• C. Osteons
• D. Central canals

Answer: (B)

Osteocytes live in tiny pockets within the bone matrix called lacunae. These small cavities cradle the mature bone cells, keeping them surrounded by mineralized bone while still allowing nutrients to diffuse in. The cells connect to each other through thin channels called canaliculi, forming a network for communication and nutrient exchange. Osteons are the cylindrical units of compact bone, each with a central canal housing blood vessels, and central canals are part of that organization. So the small cavities that actually hold osteocytes are lacunae.
