canaliculus

 [kan″ah-lik´u-lus] (pl. canali´culi) (L.)
an extremely narrow tubular passage or channel. adj., adj canalic´ular.
bile canaliculi fine tubular channels forming a three-dimensional network within the parenchyma of the liver. They join to form the bile ductules and eventually the hepatic duct.
bone canaliculi branching tubular passages radiating like wheel spokes from each bone lacuna to connect with the canaliculi of adjacent lacunae, and with the haversian canal.
lacrimal canaliculus the short passage in an eyelid, beginning at the lacrimal point and draining tears from the lacrimal lake to the lacrimal sac; called also lacrimal duct. See also lacrimal apparatus.
mastoid canaliculus a small channel in the temporal bone transmitting the auricular branch of the vagus nerve.

mas·toid can·a·lic·u·lus

[TA]
the canal that extends from the jugular fossa laterally through the mastoid process. It transmits the auricular branch of the vagus.

mas·toid ca·nal·i·cu·lus

(mas'toyd kan'ă-lik'yŭ-lŭs) [TA]
