The parasympathetic fibers that travel in the facial nerve originate in the superior salivatory nucleus. Nuclei nucleus ambiguus spinal accessory nucleus Cranial Spinal. The nerve arises in the ponsan area of the brainstem. Facial nerve Cranial nerve VII. Innervates the muscles of facial expression, the posterior belly of the digastric, the stylohyoid and the stapedius muscles. These innervate the muscles of facial expression:. It provides motor innervation to the some of the muscles around the ear.
Where does the facial nerve divide into its terminal motor branches?
The Facial Nerve (CN VII)
The muscles of facial expression will be paralysed or severely weakened. The axons of type SVA, special visceral afferentprovide taste to the anterior two-thirds of tongue via chorda tympani. The facial and intermediate nerves can be collectively referred to as the nervus intermediofacialis. Intra operatively the facial nerve is recognized at 3 constant landmarks: Parasympathetic innervation serves to increase the flow of saliva from these glands.
