General sensory information from the upper pharynx and posterior one-third of the tongue travel via the pharyngeal branches of CN IX. These peripheral processes have their cell body in either the superior or inferior glossopharyngeal ganglion.
11 kwi 2019 · Glossopharyngeal nerve branches. Here is a short summary of the branches of the glossopharyngeal nerve and their functions: Tympanic: sensory innervation to the mucosa of the middle ear, turning into the lesser petrosal nerve to supply parasympathetic fibres to the parotid gland* Stylopharyngeus: motor innervation to the stylopharyngeus
23 wrz 2023 · Branches: Key branches include the tympanic nerve (which contributes to the tympanic plexus), pharyngeal branches, carotid sinus nerve, and lingual branches for taste and sensation.
7 lis 2022 · The glossopharyngeal nerve carries sensory, efferent motor, and parasympathetic fibers. Its branches consist of tympanic, tonsillar, stylopharyngeal, carotid sinus nerve, branches to the tongue, lingual branches, and a communicating branch to cranial nerve X (vagus nerve). See Image. The Glossopharyngeal Nerve.
Together with branches of the vagus nerve (CN X) and laryngopharyngeal nerve of the cervical sympathetic trunk, these branches participate in forming the pharyngeal nerve plexus on the posterior wall of the pharynx.
