| sphenopalatine ganglion | 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) |

| spinal 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) |
| spiral cochlear ganglion | 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) |
| spiral ganglion | The sensory ganglion of the cochlear nerve. The cells of the spiral ganglion send fibres peripherally to the cochlear hair cells and centrally to the cochlear nuclei of the brainstem. (12 Dec 1998) |
| spiral ganglion of cochlea | 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) |
| splanchnic ganglion | Ha small sympathetic ganglion often present in the course of the greater splanchnic nerve. Synonym: ganglion splanchnicum, Lobstein's ganglion. (05 Mar 2000) |
| nasal ganglion | 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) |
| stellate ganglion | A paravertebral sympathetic ganglion formed by the fusion of the inferior cervical and first thoracic ganglia. (12 Dec 1998) |
| neural ganglion | 1. A knot or knotlike mass. 2. <anatomy> A general term for a group of nerve cell bodies located outside the central nervous system, occasionally applied to certain nuclear groups within the brain or spinal cord, for example basal ganglia. 3. <oncology, tumour> A benign cystic tumour occurring on a aponeurosis or tendon, as in the wrist or dorsum of the foot, it consists of a thin fibrous capsule enclosing a clear mucinous fluid. (18 Nov 1997) |
| nodose ganglion | The inferior (caudal) ganglion of the vagus (10th cranial) nerve. The unipolar nodose ganglion cells are sensory cells with central projections to the medulla and peripheral processes traveling in various branches of the vagus nerve. (12 Dec 1998) |
| sublingual ganglion | 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) |
| submandibular ganglion | 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) |
| submaxillary ganglion | 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) |
| superior cervical ganglion | The largest and uppermost of the paravertebral sympathetic ganglia. (12 Dec 1998) |
| superior mesenteric ganglion | A paired sympathetic ganglion located at the origin of the superior mesenteric artery from the aorta. Synonym: ganglion mesentericum superius. (05 Mar 2000) |
