MICROANATOMY

Detailed explanation-1: -Answer and Explanation: The small spaces in bone tissue that are holes in which osteocytes live are called A. Lacunae. The lacunae house the osteocytes while canaliculi (small tunnels) connect the lacunae to the central canal so osteocytes can receive oxygen and nutrients via the blood.

Detailed explanation-2: -compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.

Detailed explanation-3: -Osteocytes are most often described as terminally differentiated osteoblasts that reside in small pockets termed lacunae, located deep within mineralized bone.
