| auditory 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) |

| auricular 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) |
| Bezold's ganglion | An aggregation of nerve cells in the interatrial septum. (05 Mar 2000) |
| Bochdalek's ganglion | A ganglion of the plexus of the dental nerve lying in the maxilla just above the root of the canine tooth. (05 Mar 2000) |
| Bock'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) |
| Bottcher's ganglion | Ganglion on the cochlear nerve in the internal acoustic meatus. (05 Mar 2000) |
| branch to trigeminal ganglion | Ganglionic branch of internal carotid artery. (05 Mar 2000) |
| Valentin's ganglion | A ganglion on the superior alveolar nerve. (05 Mar 2000) |
| 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) |
| ganglion cell | <pathology> A type of interneuron that conveys information from the retinal bipolar, horizontal and amacrine cells to the brain. (18 Nov 1997) |
| ganglion cells of dorsal spinal root | Pseudounipolar nerve cell bodies in the ganglia of the dorsal spinal nerve roots; the sensory spinal nerves are composed of the peripheral axon branches of these sensory ganglion cell's, whereas the central axon branch of each such cell enters the spinal cord as a component of the dorsal root. (05 Mar 2000) |
| ganglion cells of retina | The nerve cell's of the retina whose central processes (fibres) form the optic nerve; their peripheral processes synapse with the bipolar cell's and through them with the rod and cone cell's; these cell bodies are round or flask-shaped and vary considerably in size. (05 Mar 2000) |
| ganglion cervicale inferius | Inferior-most of the three ganglia of the cervical portion of the sympathetic trunk, occurring at the C7 vertebral level. Most commonly, it is fused to the first thoracic sympathetic ganglion to form a stellate ganglion. Synonym: ganglion cervicale inferius. (05 Mar 2000) |
| ganglion cervicale medium | A sympathetic ganglion, of small size and sometimes absent; located at the level of the cricoid cartilage. Synonym: ganglion cervicale medium. (05 Mar 2000) |
| ganglion cervicale superius | The largest and uppermost of the paravertebral sympathetic ganglia. (12 Dec 1998) |
