| retinal ganglion cells | Cells of the innermost nuclear layer of the retina, the ganglion cell layer, which project axons through the optic nerve to the brain. They are quite variable in size and in the shapes of their dendritic arbors, which are generally confined to the inner plexiform layer. (12 Dec 1998) |

| cervicothoracic ganglion | A sympathetic trunk ganglion lying behind the subclavian artery near the origin of the vertebral artery, it is formed by the fusion of the inferior cervical ganglion, at the level of the seventh cervical vertebra, with the first thoracic ganglion. Synonym: ganglion stellatum, stellate ganglion. (05 Mar 2000) |
| periosteal ganglion | A flattened subperiosteal cavity containing clear, yellow, viscous, synovial-like fluid. (05 Mar 2000) |
| Ribes' ganglion | A small sympathetic ganglion situated on the anterior communicating artery of the brain. (05 Mar 2000) |
| Gudden's ganglion | 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) |
| petrous ganglion | <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) |
| pharyngeal branch of pterygopalatine ganglion | Branch of pterygopalatine ganglion passing posteriorly through pharyngeal canal to supply postsynaptic parasympathetic fibres to mucus glands of nasopharynx. Synonym: ramus pharyngeus ganglii pterygopalatini, Bock's nerve. (05 Mar 2000) |
| ciliary ganglion | <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) |
| middle cervical ganglion | A sympathetic ganglion, of small size and sometimes absent; located at the level of the cricoid cartilage. Synonym: ganglion cervicale medium. (05 Mar 2000) |
| Walther's ganglion | The most inferior, unpaired ganglion of the sympathetic trunk; inconstant. Synonym: coccygeal ganglion, Walther's ganglion. (05 Mar 2000) |
| coccygeal ganglion | The most inferior, unpaired ganglion of the sympathetic trunk; inconstant. Synonym: coccygeal ganglion, Walther's ganglion. (05 Mar 2000) |
| 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) |
| communicating branch of otic ganglion to auriculotemporal nerve | <anatomy, nerve> A branch of the otic ganglion joining the roots of the auriculotemporal nerve to convey postsynaptic parasympathetic fibres to the parotid gland. Synonym: ramus communicans ganglii otici cum nervo auriculotemporali. (05 Mar 2000) |
| communicating branch of otic ganglion to chorda tympani | A small branch of the otic ganglion conveying sensory fibres to the chorda tympani. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of otic ganglion with medial pterygoid nerve | <anatomy, nerve> Branch of otic ganglion joining the nerve to the medial pterygoid muscle. Synonym: ramus communicans ganglii otici cum nervo pterygoideo mediali. (05 Mar 2000) |
