Nasolacrimal drainage apparatus

A.Prof Frank Gaillard and Dr Henry Knipe et al.

The nasolacrimal (drainage) apparatus consists of:

Tears produced by the lacrimal gland, accessory lacrimal glands of Krause Wolfring and Zeis, and Meibomian glands track medially along the eyelid margins and collect at the lacrimal lake at the inner canthus. The nasolacrimal drainage apparatus drains tears in a descending course through the lacrimal canaliculi, lacrimal sac, and nasolacrimal duct to the inferior nasal meatus below the inferior turbinate in the nasal cavity

Note that the nasolacrimal apparatus is not to be confused with the lacrimal apparatus, which also includes the lacrimal gland.
