a small tubuloalveolar gland secreting tears that bathe and moisten the anterior surfaces of the eyeball and conjunctiva. The lacrimal gland is lodged in a depression of the frontal bone at the outer angle of the orbit. The conjunctiva also has small accessory lacrimal glands that are portions of the lacrimal gland. The efferent ducts of the lacrimal gland open into the conjunctival sac. The gland is innervated by secretory centrifugal fibers of the facial nerve.
