Supraorbital nerve
The supraorbital nerve is one of two terminal branches - the other being the supratrochlear nerve - of the frontal nerve (itself a branch of the ophthalmic nerve (CN V1)). It exits the orbit via the supraorbital foramen/notch before splitting into a medial branch and a lateral branch. It innervates the skin of the forehead, upper eyelid, and the root of the nose.
