Lacrimal Nerve

The lacrimal nerve arises from ophthalmic nerve, which in turn originates from trigeminal nerve. It enters the orbit through the superior orbital fissure. As the lacrimal nerve enters the lacrimal gland, it gives off several filaments, supplying sensory innervation to the gland, the conjunctiva, the lateral commissure of eye, and skin of upper eyelid. It is a general sensory nerve.
