The pharyngeal plexus is a network of nerve fibers innervating most of the palate, larynx, and pharynx.
It is located on the surface of the middle pharyngeal constrictor muscle.[1]

Edit
Although the Terminologia Anatomica name of the plexus has "vagus nerve" in the title, other nerves make contributions to the plexus.
It has the following sources:[2]
- CN IX - pharyngeal branches of glossopharyngeal nerve - sensory
- CN X - pharyngeal branch of vagus nerve - motor
- superior cervical ganglion sympathetic fibers - vasomotor
Because the cranial part of accessory nerve (CN XI) leaves the jugular foramen along with CN IX and X, it is sometimes considered part of the plexus as well.[2]
InnervationEdit
SensoryEdit
The pharyngeal plexus provides sensory innervation of the oropharynx and laryngopharynx from CN IX and CN X. (The nasopharynx is innervated by CN V2)
MotorEdit
The pharyngeal plexus, with fibers from CN IX, CN X, and cranial part of CN XI, innervates all the muscles of the pharynx (except stylopharyngeus, which is innervated directly by a branch of CN IX).
This includes the following muscles: palatopharyngeus, levator veli palatini, palatoglossus, and musculus uvulae, the pharyngeal constrictors, plus others.
