The lacrimal canaliculi, one in each eyelid, commence at minute orifices, the lacrimal punctum (puncta lacrimalia; lacrimal point), on the summits of the papillae lacrimales, seen on the margins of the lids at the lateral extremity of the lacus lacrimalis. There are two lacrimal puncta in the medial (inside) portion of each eye.
