Anatomical terms of neuroanatomy

The pharyngeal plexus is a nerve plexus located upon the outer surface of the pharynx. It contains a motor component (derived from the vagus nerve (cranial nerve X)), a sensory component (derived from the glossopharyngeal nerve (cranial nerve IX)), and sympathetic component (derived from the superior cervical ganglion).[1]

The plexus provides motor innervation to most muscles of the soft palate (all but the tensor veli palatini muscle) and most muscles of the pharynx (all but the stylopharyngeus muscle).[1] The larynx meanwhile receives motor innervation from the vagus nerve (CN X) via its external branch of the superior laryngeal nerve and its recurrent laryngeal nerve, and not through the pharyngeal plexus.[citation needed]
