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.
