Nerves of the pharyngeal plexus?

Explanation:
The pharyngeal plexus is a network on the pharyngeal wall formed by the pharyngeal branches of two cranial nerves, with sympathetic fibers hitching rides with the vessels. The glossopharyngeal (CN IX) and vagus (CN X) contribute to this plexus, and sympathetic fibers from the superior cervical ganglion accompany vessels into the area. That combination—CN IX, CN X, and sympathetic fibers—is why these are listed as the nerves of the pharyngeal plexus. The tensor veli palatini, although nearby, is innervated by V3 directly and does not form part of the plexus, which is why V3 isn’t considered a contributor to the pharyngeal plexus.
