	Anatomical terms of neuroanatomy

The pharyngeal branch of the vagus nerve is the principal motor nerve of the pharynx. It represents the motor component of the pharyngeal plexus of vagus nerve and ultimately provides motor innervation to most of the muscles of the soft palate (all but the tensor veli palatini muscle), and of the pharynx (all but the stylopharyngeus muscle).^[1]

The neuron cell bodies of the axons of the pharyngeal branch reside in the nucleus ambiguus. The pharyngeal branch arises from the superior portion of the inferior ganglion of vagus nerve. It passes in between the external carotid artery and internal carotid artery; upon reaching the superior border of the middle pharyngeal constrictor muscle the nerve ramifies into numerous filaments that contribute to the formation of the pharyngeal plexus.^[1]
