This nerve is sensory, and its fibres are in part distributed to the skin of the cheek (communi- cating with buccal branches of the facial nerve); they are also in part distributed to the mucous membrane of the inside of the mouth, to reach which they pierce Tympanic plexus Tympanic branch of glossopharyngeal Facial nerve 1 Genicular ganglion Caroticotympanic nerve I Lesser superficial petrosal nerve .
