Lacrimal Drainage System Anatomy - Diagram and Explanation #2052860 (License: Personal Use)

This anatomical illustration depicts the complete lacrimal drainage pathway: starting at the lacrimal gland (1), tears spread across the ocular surface, enter the puncta (3), traverse the canaliculi (4), collect in the lacrimal sac (5), and drain via the nasolacrimal duct (6) into the inferior meatus of the nasal cavity (2). Key nerves and vessels-including the infraorbital nerve (7), zygomaticotemporal branch (8), and facial artery (9)-are also shown for contextual orientation.

Used in ophthalmology education, patient counseling, and clinical reference materials to explain epiphora, dacryocystitis, or surgical planning (e.g., DCR). Matches user intent for understanding tear drainage disorders or anatomy study.
