Explanation:
Detailed explanation-1: -Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.
Detailed explanation-2: -Bone lacunae are small, spindle-shaped spaces (appearing dark in this image), each containing an osteocyte that is left behind by osteoblasts during the process of remodelling. The long axis of each lacuna lies parallel to the lamella within which it resides.
