| geniculate | Bent abruptly like a knee joint. (09 Oct 1997) |
|---|---|
| geniculate bodies | Part of the diencephalon inferior to the caudal end of the dorsal thalamus. Includes the lateral geniculate body which relays visual impulses from the optic tract to the calcarine cortex, and the medial geniculate body which relays auditory impulses from the lateral lemniscus to the auditory cortex. (12 Dec 1998) |
| geniculate body | See: lateral geniculate body, medial geniculate body. (05 Mar 2000) |
| geniculate ganglion | 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) |
| geniculate neuralgia | A severe paroxysmal lancinating pain deep in the ear, on the anterior wall of the external meatus, and on a small area just in front of the pinna. Synonym: geniculate otalgia, Hunt's neuralgia, neuralgia facialis vera. (05 Mar 2000) |
| geniculate otalgia | A severe paroxysmal lancinating pain deep in the ear, on the anterior wall of the external meatus, and on a small area just in front of the pinna. Synonym: geniculate otalgia, Hunt's neuralgia, neuralgia facialis vera. (05 Mar 2000) |
| geniculate zoster | Herpes zoster involving the facial and auditory nerves associated with ipsilateral facial paralysis, usually transitory, and herpetic vesicles of the external ear or tympanic membrane, which also may or may not be associated with tinnitus, vertigo, and hearing disorders. (12 Dec 1998) |
| geniculated | Bent abruptly like a knee joint. (09 Oct 1997) |
| medial geniculate body | The medial one of a pair of prominent cell groups in the posteroinferior parts of the thalamus; it functions as the last of a series of processing stations along the auditory conduction pathway to the cerebral cortex, receiving the brachium of the inferior colliculus and giving rise to the auditory radiation to the auditory cortex in the superior temporal gyrus. Synonym: corpus geniculatum mediale, corpus geniculatum internum. (05 Mar 2000) |
|---|---|
| nucleus of lateral geniculate body | Nucleus of the thalamus characterised by six layers of cells, two parvicellular, four magnocellular, alternating with thin layers of fibres; receives bilateral visual input, projects to calcarine cortex. (05 Mar 2000) |
| nucleus of medial geniculate body | The nerve cell groups composing the medial geniculate body (corpus geniculatum mediale). Synonym: nucleus corporis geniculati medialis. (05 Mar 2000) |
| lateral geniculate body | The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe. Synonym: corpus geniculatum laterale, corpus geniculatum externum. (05 Mar 2000) |
