The
lacrimal canaliculi, one in each
eyelid, commence at minute orifices, termed
puncta lacrimalia (or
lacrimal punctum, or
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.
