Superior laterally in the orbit,
0:02
one finds the lacrimal gland, and medially,
0:06
one has the lacrimal sac.
0:09
The tears are produced by the lacrimal gland and flow
0:13
across the eye from lateral to medial and they are
0:16
collected in the superior and inferior
0:19
lacrimal canaliculi.
0:22
From the superior and inferior canaliculi,
0:24
the tear ducts pass through the sinus of Maier
0:29
to get to the lacrimal sac. To get from the lacrimal
0:33
sac to the nasolacrimal duct, one must
0:37
pass through the valve of Krause.
0:41
The lacrimal duct extends inferiorly and at the
0:46
inferiormost portion, one has the valve of Hasner
0:52
which leads from the nasolacrimal duct to just
0:57
under the inferior turbinate within the nasal cavity.
