Temporal Branch Of Facial Nerve
The temporal branches of the facial nerve (frontal branch of the facial nerve) crosses the zygomatic arch to the temporal region, supplying the auriculares anterior and superior, and joining with the zygomaticotemporal branch of the maxillary nerve, and with the auriculotemporal branch of the mandibular nerve. The more anterior branches supply the frontalis muscle, frontalis, the orbicularis oculi, and corrugator supercilii, and join the Supraorbital nerve, supraorbital and Lacrimal nerve, lacrimal branches of the Ophthalmic nerve, ophthalmic. The temporal branch acts as the efferent limb of the corneal reflex. Anatomic location The temporal branch of the facial nerve is typically found between the temporoparietal fascia (i.e., superficial temporal fascia) and temporal fascia (i.e., deep temporal fascia). This layer is also known as the innominate fascia. There are several methods using anatomic landmarks that may be used to find the temporal branch of the facial nerve. One metho ...

Facial Nerve
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. The nerve typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen. It arises from the brainstem from an area posterior to the cranial nerve VI (abducens nerve) and anterior to cranial nerve VIII (vestibulocochlear nerve). The facial nerve also supplies preganglionic parasympathetic fibers to several head and neck ganglia. The facial and intermediate nerves can be collectively referred to as the nervus intermediofacialis. The path of the facial nerve can be divided into six segments: # intracranial (cisternal) segment (from brainstem pons to internal auditory canal) # meatal (canalicular) segment (with ...
