ANATOMY

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: -Osteocyte cells are embedded in the mineralized matrix in protected lacunae which surround the cell body. The cells are connected to one another by dendritic cell processes which reside in canaliculi. Together, these form the lacunar–canalicular network (LCN).

Detailed explanation-3: -Chondrocytes are located in the cartilage of the body and osteocytes are located in the bone. Chondrocytes reside in tiny pockets called lacunae that are in the center of cartilage deposits.

Detailed explanation-4: -Lacunae are spaces in which bone cells are present. The main purpose of a lacuna in bone or cartilage is to provide a home for the cells it contains while also keeping them alive and functional. In bones, lacunae encase osteocytes; in cartilage, lacunae enclose chondrocytes.

Detailed explanation-5: -Osteocytes, the cells residing within the bone matrix, make up between 90% to 95% of the cellular component in skeletally mature adult bone tissue.
