Lateral Condyle A canaliculus is an anatomical term used to describe a small passageway. Examples include: • • • • • Canaliculus (bone), a small channel found in ossified bone Canaliculus (parietal cell), an adaptation found on gastric parietal cells The lacrimal canaliculi, canaliculi, several small ducts in the eye The dental canaliculi, canaliculi, the blood supply within a tooth Bile canaliculi, canaliculi, where the bile produced by the hepatocytes is drained
