Temporal Region
摘要
The temporal branches of the facial nerve leave the parotid gland immediately inferior to the zygomatic arch. The nerve provides motor innervation to the frontalis, upper part of the orbicularis oculi, corrugator muscles, and possibly the procerus muscle. There are three to four temporal branches, and a branch of the posterior division innervates the superior auricular muscle. The posterior and middle divisions innervate the frontalis muscle, while the middle and anterior divisions innervate the corrugator supercilii and the lateral part of the orbicularis oculi muscles.
