What are the small cavities that house osteocytes called?

• A. Osteocytes
• B. Lacunae
• C. Canaliculi
• D. Matrix

Answer: (B)

The main idea here is where osteocytes live within bone tissue. Osteocytes are the mature bone cells that maintain the mineralized matrix, and they sit inside tiny hollow spaces in that matrix called lacunae. These lacunae form a network connected by very small channels called canaliculi, which allow nutrients and signals to pass between cells. So, the small cavities that house osteocytes are lacunae. The other terms refer to the cells themselves (osteocytes), the tiny channels (canaliculi), or the bone material (matrix), not the cavities that hold the cells.
