what does it innervate?
The principal contributors to this plexus are
the tympanic branch of the glossopharyngeal nerve (IX) and branches from the internal
carotid plexus,
it innervates the mucous membrane of the middle ear, the mastoid area and the pharyngotympanic tube. The lesser petrosal nerve leaves the plexus and travels across the anterior surface of the petrous part of the temporal bone, eventually to leave the
middle cranial fossa through the foramen ovale and enter the otic ganglion.
