Canaliculi is a tunnel containing processes of osteocytes extending from the lacunae into and through the substance of the mineralized matrix. Each canaliculus connects with its neighbor bridging communication between the two osteocytes.
Fine channels through bone that form an anastomising network between the osteocyte lacunae. In living bone the canaliculi are occupied by the cytoplasmic processes of the osteocytes.
Microscopic passageways between cells; bile canaliculi carry bile to bile ducts in the liver; in bone, canaliculi permit the diffusion of nutrients and wastes to and from osteocytes.
