NEET PG DENTAL EXAM

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: -Osteocytes in their lacunae are now being appreciated for their dynamic functions in homeostatic adaptation of bone to mechanical forces [177]. Osteocytes maintain bone mass through anabolic activities and even as a dying osteocyte, they promote bone repair through recruitment of osteoclast mediated turnover.

Detailed explanation-3: -Spongy (Cancellous) Bone. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles.
