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: -The dental canaliculi (sometimes called dentinal tubules) are the blood supply of a tooth. Odontoblast process run in the canaliculi that transverse the dentin layer and are referred as dentinal tubules.

Detailed explanation-3: -Canaliculi-tiny canals that connect all the lacunae.

Detailed explanation-4: -Bone canaliculi are small canals running through the bone solid matrix, hosting osteocyte’s dendrites, and saturated by an interstitial fluid rich in ions. Because of the small size of these canals (few hundred nanometers in diameter), fluid flow is coupled with electrochemical phenomena.

Detailed explanation-5: -Osteocytes sit in the calcified matrix, in small spaces called lacunae (lacuna-singular). Long processes from the osteocyte lie in small channels called canaliculi (small canals). These are channels for the transport for nutrients and waste.
