Bone matrix
The narrowest components of the tunnel system within bone matrix are canaliculi, which pass between adjacent osteocyte lacunae. Osteocytes extend numerous, fine cytoplasmic processes that lie in the canaliculi. Processes from adjacent osteocytes are interconnected by gap junctions that allow for the transfer of nutrients and wastes between osteocytes as well as between the innermost osteocytes and the Haversian blood vessels. Canaliculi are not lined by endosteum. Ground, compact bone, 1000x
