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 (Ot) are located within lacunae surrounded by mineralized bone matrix (B).

Detailed explanation-3: -Osteoclasts lie in small cavities called Howship’s lacunae, formed from the digestion of the underlying bone.

Detailed explanation-4: -Lacuna in anatomy In anatomy, a lacuna is defined as the space housing the osteocytes in bones and chondrocytes in cartilage.

Detailed explanation-5: -Osteoblasts are located immediately above the osteoid (newly formed bone matrix). Osteocytes are found within lacunae. Giant multinucleated osteoclasts, which break down bone, are occasionally found in lacunae termed Howship’s lacunae.
