Temporal branches of the facial nerve
The more anterior branches supply the frontalis, the orbicularis oculi, and corrugator supercilii, and join the supraorbital and lacrimal branches of the ophthalmic.The temporal branch acts as the efferent limb of the corneal reflex.There are several methods using anatomic landmarks that may be used to find the temporal branch of the facial nerve.To test the function of the temporal branches of the facial nerve, a patient is asked to frown and wrinkle their forehead.This article incorporates text in the public domain from page 905 of the 20th edition of Gray's Anatomy (1918)
