| ganglion mesentericum inferius | The lowest of the sympathetic prevertebral ganglia, located at the origin of the inferior mesenteric artery from the aorta and containing the sympathetic neurons innervating the descending and sigmoid colon. Synonym: ganglion mesentericum inferius. (05 Mar 2000) |
|---|---|
| ganglion mesentericum superius | A paired sympathetic ganglion located at the origin of the superior mesenteric artery from the aorta. Synonym: ganglion mesentericum superius. (05 Mar 2000) |
| ganglion of facial nerve | The sensory ganglion of the facial (7th cranial) nerve. The geniculate ganglion cells send central processes to the brainstem and peripheral processes to the taste buds in the anterior tongue, the soft palate, and the skin of the external auditory meatus and the mastoid process. (12 Dec 1998) |
| ganglion of intermediate nerve | The sensory ganglion of the facial (7th cranial) nerve. The geniculate ganglion cells send central processes to the brainstem and peripheral processes to the taste buds in the anterior tongue, the soft palate, and the skin of the external auditory meatus and the mastoid process. (12 Dec 1998) |
| ganglion of nervus intermedius | The sensory ganglion of the facial (7th cranial) nerve. The geniculate ganglion cells send central processes to the brainstem and peripheral processes to the taste buds in the anterior tongue, the soft palate, and the skin of the external auditory meatus and the mastoid process. (12 Dec 1998) |
| ganglion of trunk of vagus | <anatomy, nerve> A large sensory ganglion of the vagus, anterior to the internal jugular vein. Synonym: ganglion inferius nervi vagi, ganglion of trunk of vagus, nodose ganglion. (05 Mar 2000) |
| ganglion oticum | 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) |
| ganglion pterygopalatinum | A small parasympathetic ganglion in the upper part of the pterygopalatine fossa whose postsynaptic fibres supply the lacrimal, nasal, palatine and pharyngeal glands. Synonym: ganglion pterygopalatinum, Meckel's ganglion, nasal ganglion, sphenopalatine ganglion. (05 Mar 2000) |
| ganglion ridge | A group of embryonic cells that separate from the neural plate during neurulation and migrate to give several different lineages of adult cells: the spinal and autonomic ganglia, the glial cells of the peripheral nervous system and nonneuronal cells, such as chromaffin cells, melanocytes and some haemopoietic cells. (18 Nov 1997) |
| ganglion spinale | <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) |
| ganglion spirale cochleae | An elongated ganglion of bipolar sensory nerve cell bodies on the cochlear part of the vestibulocochlear nerve in the spiral canal of the modiolus; each ganglion cell gives rise to a peripheral process that passes between the layers of the bony spiral lamina to the organ of Corti, and a central axon that enters the hindbrain as a component of the inferior (cochlear) root of the eighth nerve. Synonym: ganglion spirale cochleae, auditory ganglion, cochlear ganglion, Corti's ganglion, spiral cochlear ganglion. (05 Mar 2000) |
| ganglion splanchnicum | Ha small sympathetic ganglion often present in the course of the greater splanchnic nerve. Synonym: ganglion splanchnicum, Lobstein's ganglion. (05 Mar 2000) |
| ganglion stellatum | An alternate term for cervicothoracic ganglion. (05 Mar 2000) |
| ganglion sublinguale | A tiny ganglion occasionally found anterior to the submandibular ganglion, of which it is a displaced portion; innervates the sublingual gland. Synonym: ganglion sublinguale. (05 Mar 2000) |
| ganglion submandibulare | A small parasympathetic ganglion suspended from the lingual nerve; its postganglionic branches go to the submandibular and sublingual glands; its preganglionic fibres come from the superior salvatory nucleus by way of the chorda tympani. Synonym: ganglion submandibulare, submaxillary ganglion. (05 Mar 2000) |
