Anatomy and Function - 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. - It provides motor innervation to most of the muscles of the soft palate and pharynx. - 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.

Origin - It is unclear whether the cranial root of accessory nerve (CN XI) contributes significant nerve fibers to the CN X that would then constitute the pharyngeal branch.
