The tear gland of the eye of humans and other
vertebrates. It lies beneath the upper eyelid, in a slight depression in
the orbital cavity. The lacrimal gland is controled by the autonomic
nervous system. It continuously secretes small amounts of sterile, slightly
antiseptic, tears which keep the cornea
moist. Tears drain away through two small openings (puncta)
at the inner corner of the eye into the lacrimal caniculi.
From there the tears pass into the nasal cavity (see nose)
via the lacrimal sac and nasolacrimal duct,
or also known as the tear duct.
