| 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) |
| 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 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) |
