Its three branches are the ophthalmic v1 maxillary v2 and mandibular v3. Each of those branches supplies the corresponding region on the face. It conveys some sensory information from the tongue and the interior of the mouth.

The facial nerve is the nerve associated with the second pharyngeal arch. Although at first glance it is the motor nerve of facial expression which begins as a trunk and emerges from the parotid gland as five branches see facial nerve branches mnemonic it has taste and parasympathetic fibers that relay in a complex manner. This nerve performs two major functions.

It is one of the longest cranial nerves extending from the brainstem to the terminal end branches which are located throughout the face. The specific bones and muscles derived from the second pharyngeal arch are shown below. The sensory innervation to the face comes from the trigeminal nerve which is the only cranial nerve that arises directly from the pons.

Several structures of the facial nervedescribed as nuclei segments and branchesproduce the four components of facial nerve function. It 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 facial nerve is one of a group of nerves called the cranial nerves cn twelve pairs of nerves that with the exception of the spinal accessory nerve cn xi originate in the brain and contribute to the peripheral nervous system pns.
