| 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) |
| ganglion cervicothoracicum | A sympathetic trunk ganglion lying behind the subclavian artery near the origin of the vertebral artery, at the level of the seventh cervical vertebra, close to the first thoracic ganglion with which it is usually fused. (05 Mar 2000) |
| ganglion ciliare | <anatomy, neurology> Neural crest derived ganglion acting as relay between parasympathetic neurons of the oculomotor nucleus in the midbrain and the muscles regulating the diameter of the pupil of the eye. (18 Nov 1997) |
| ganglion cyst | <dermatology, tumour> A small cystic tumour, composed of ganglion cells, containing viscous fluid and connected either with a joint membrane or a tendon sheath. Commonly found on the back of the wrist, hands or feet. (27 Sep 1997) |
| ganglion extracraniale | <anatomy, nerve> The lower of two sensory ganglion's on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym: ganglion inferius nervi glossopharyngei, Andersch's ganglion, extracranial ganglia, ganglion extracraniale, petrosal ganglion, petrous ganglion. (05 Mar 2000) |
| ganglion geniculi | 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 habenulae | The gray matter of the habenula, composed of a small-celled medial and a larger-celled lateral habenular nucleus; both nuclei receive fibres from basal forebrain regions (septum, basal nucleus, lateral preoptic nucleus); the lateral habenular nucleus receives an additional projection from the medial segment of the globus pallidus. Both nuclei project by way of the retroflex fasciculus to the interpeduncular nucleus and a medial zone of the midbrain tegmentum. Synonym: nucleus habenulae, ganglion habenulae. (05 Mar 2000) |
| ganglion impar | The most inferior, unpaired ganglion of the sympathetic trunk; inconstant. Synonym: coccygeal ganglion, Walther's ganglion. (05 Mar 2000) |
| ganglion inferius nervi glossopharyngei | <anatomy, nerve> The lower of two sensory ganglion's on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym: ganglion inferius nervi glossopharyngei, Andersch's ganglion, extracranial ganglia, ganglion extracraniale, petrosal ganglion, petrous ganglion. (05 Mar 2000) |
| ganglion inferius nervi vagi | <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 isthmi | 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) |
