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: -Canaliculi-tiny canals that connect all the lacunae.

Detailed explanation-3: -Together, the osteocyte lacunae and canaliculi comprise the lacunocanalicular system. This system allows for the flow of canalicular fluid in the lacunocanalicular space that carries nutrients and signaling factors to and from the osteocytes via the circulation.

Detailed explanation-4: -They are networked to each other via long cytoplasmic extensions that occupy tiny canals called canaliculi, which are used for exchange of nutrients and waste through gap junctions.

Detailed explanation-5: -Canalicular fluid flow is acknowledged to play a major role in bone functioning, allowing bone cells’ metabolism and activity and providing an efficient way for cell-to-cell communication.
