| interpeduncular ganglion | A median, unpaired, ovoid cell group at the base of the midbrain tegmentum between the cerebral peduncles; it receives the retroflex fasciculus from the habenula, and projects to the raphe region (raphe nuclei) and periaqueductal gray substance of the midbrain. Synonym: nucleus interpeduncularis, ganglion isthmi, Gudden's ganglion, intercrural ganglion, interpeduncular ganglion. (05 Mar 2000) |

| intervertebral ganglion | <anatomy> Enlargement of the dorsal root of the spinal cord containing cell bodies of afferent spinal neurons. Neural outgrowth from dorsal root ganglia has been studied extensively in vitro. (18 Nov 1997) |
| intracranial ganglion | <anatomy, nerve> The upper and smaller of two ganglia on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym: ganglion superius nervi glossopharyngei, Ehrenritter's ganglion, intracranial ganglion, jugular ganglion. (05 Mar 2000) |
| orbital branch of pterygopalatine ganglion | Branches of pterygopalatine ganglion traversing inferior orbital fissure, distributed in orbit to periorbita and mucosa of ethmoidal and sphenoidal sinuses. Synonym: ramus orbitalis ganglii pterygopalatini. (05 Mar 2000) |
| otic ganglion | An autonomic ganglion situated below the foramen ovale medial to the mandibular nerve; its postganglionic, parasympathetic fibres are distributed to the parotid gland. Synonym: ganglion oticum, Arnold's ganglion, auricular ganglion, otoganglion. (05 Mar 2000) |
| terminal ganglion | One of the cells located along the terminal nerves, one of the scattered postganglionic autonomic neurons located in or close to the wall of the organ innervated; they are usually parasympathetic. Synonym: ganglion terminale. (05 Mar 2000) |
| Ehrenritter's ganglion | <anatomy, nerve> The upper and smaller of two ganglia on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym: ganglion superius nervi glossopharyngei, Ehrenritter's ganglion, intracranial ganglion, jugular ganglion. (05 Mar 2000) |
| trigeminal ganglion | The semilunar-shaped ganglion containing the cells of origin of most of the sensory fibres of the trigeminal nerve. It is situated within the dural cleft on the cerebral surface of the petrous portion of the temporal bone and gives off the ophthalmic, maxillary, and part of the mandibular nerves. (12 Dec 1998) |
| Troisier's ganglion | Historic term for a lymph node immediately above the clavicle, especially on the left side, that is palpably enlarged as the result of a metastasis from a malignant neoplasm; the presence of such a node indicates that the probable site of primary involvement is in an abdominal organ. See: signal node. Synonym: Troisier's node. (05 Mar 2000) |
| tympanic ganglion | A small ganglion on the tympanic nerve during its passage through the petrous portion of the temporal bone. Synonym: ganglion tympanicum. (05 Mar 2000) |
| jugular ganglion | <anatomy, nerve> The upper and smaller of two ganglia on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym: ganglion superius nervi glossopharyngei, Ehrenritter's ganglion, intracranial ganglion, jugular ganglion. (05 Mar 2000) |
| laryngopharyngeal branches of superior cervical ganglion | Branches conveying postganglionic sympathetic fibres from the superior cervical ganglion to the pharyngeal plexus. Synonym: rami laryngopharyngei ganglii cervicalis superioris. (05 Mar 2000) |
| Laumonier's ganglion | A small ganglionic swelling on filaments from the internal carotid plexus, lying on the undersurface of the carotid artery in the cavernous sinus. Synonym: Bock's ganglion, Laumonier's ganglion. (05 Mar 2000) |
| Frankenhauser's ganglion | A gangliated autonomic plexus on each side of the cervix of the uterus, derived from the inferior hypogastric plexus. Synonym: plexus uterovaginalis, Frankenhauser's ganglion, Lee's ganglion. (05 Mar 2000) |
| Lee's ganglion | A gangliated autonomic plexus on each side of the cervix of the uterus, derived from the inferior hypogastric plexus. Synonym: plexus uterovaginalis, Frankenhauser's ganglion, Lee's ganglion. (05 Mar 2000) |
