Relating to tears or tear production, including the lacrimal glands that produce tears and the lacrimal bones that help form the eye socket. Essential for eye lubrication and protection.
From Latin 'lacrima' meaning tear, related to crying or weeping. The anatomical usage developed as physicians studied the tear production system and its associated structures.
You produce about 1-2 liters of tears per year, even without crying! Your lacrimal system is like a sophisticated car wash for your eyes, constantly cleaning and protecting your cornea with a three-layer tear film that includes oils, water, and mucus.
