The superior ganglion of the glossopharyngeal nerve is a sensory ganglion of the peripheral nervous system. It is located within the jugular foramen where the glossopharyngeal nerve exits the skull. It is smaller than and superior to the inferior ganglion of the glossopharyngeal nerve. [1]
The tympanic nerve is the first branch of the glossopharyngeal nerve. It branches at the level of the inferior ganglion. Importantly, the axons which form the tympanic nerve do not synapse in this ganglion or have their cell bodies in it.
The glossopharyngeal nerve (/ ˌ ɡ l ɒ s oʊ f ə ˈ r ɪ n (d) ʒ i ə l,-ˌ f ær ən ˈ dʒ iː ə l / [1]), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, [2] is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. Being a mixed ...
Glossopharyngeal ganglion is a ganglion associated with cranial nerve IX. There are two types: There are two types: Inferior ganglion of glossopharyngeal nerve
The otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve. It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation. It is one of four parasympathetic ganglia of the head and neck.
It arises from the middle of the inferior ganglion of the vagus nerve and additionally receives a sympathetic branch from the superior cervical ganglion. The superior laryngeal nerve produces two branches: the internal laryngeal nerve (its sensory branch) which supplies sensory fibers to the laryngeal mucosa, and the external laryngeal nerve ...
trigeminal ganglion (CN V) geniculate ganglion (CN VII) spiral ganglion (CN VIII) vestibular ganglion aka Scarpa's ganglion (CN VIII) [2] superior ganglion of glossopharyngeal nerve; inferior ganglion of glossopharyngeal nerve; superior ganglion of vagus nerve; inferior ganglion of vagus nerve
The tympanic plexus is a nerve plexus within the tympanic cavity formed upon the promontory of tympanic cavity by the tympanic nerve (branch of the inferior ganglion of glossopharyngeal nerve (CN IX)), and the superior and inferior caroticotympanic nerves (post-ganglionic sympathetic branches of the internal carotid plexus).
