The pharyngeal plexus is a network of nerve fibers supplied by the pharyngeal branch of vagus nerve joining with branches from the pharyngeal branches of glossopharyngeal nerve, sympathetic fibers, and the external laryngeal nerve.
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).
