The facial canal gives passage to the facial nerve (CN VII) (hence the name). [1] [verification needed] [better source needed] Its proximal opening is at the internal auditory meatus; its distal opening is the stylomastoid foramen. In humans, the canal is approximately 3 cm long, making it the longest bony canal of a nerve in the human body.
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.
nerve of pterygoid canal through its anterior wall temporal: middle cranial fossa: carotid canal: 2: internal carotid artery: internal carotid plexus, sympathetics from the superior cervical ganglion: temporal: posterior cranial fossa: internal acoustic meatus: 2: labyrinthine artery: facial nerve (VII), vestibulocochlear nerve (VIII) temporal ...
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.
The zygomatic branches of the facial nerve (malar branches) are nerves of the face.They run across the zygomatic bone to the lateral angle of the orbit.Here, they supply the orbicularis oculi muscle, and join with filaments from the lacrimal nerve and the zygomaticofacial branch of the maxillary nerve (CN V 2).

It contains the sensory and parasympathetic fibers of the facial nerve. Upon reaching the facial canal, it joins with the motor root of the facial nerve at the geniculate ganglion. Alex Alfieri postulates that the intermediate nerve should be considered as a separate cranial nerve and not a part of the facial nerve. [4]
The geniculate ganglion (from Latin genu, for "knee" [1]) is a bilaterally paired special sense ganglion [2] of the intermediate nerve component of the facial nerve (CN VII). [3] It is situated within facial canal of the head. [citation needed]
