| ganglia of sympathetic trunk | The clusters of postganglionic neurons located at intervals along the sympathetic trunks, including the superior cervical, middle cervical, and cervicothoracic (stellate) ganglion, the thoracic, lumbar, and sacral ganglia, and the ganglion impar. Synonym: ganglia trunci sympathici, paravertebral ganglia. (05 Mar 2000) |

| ganglia, parasympathetic | Ganglia of the parasympathetic nervous system, including the ciliary, pterygopalatine, submandibular, and otic ganglia in the cranial region and intrinsic (terminal) ganglia associated with target organs in the thorax and abdomen. (12 Dec 1998) |
| ganglia pelvina | The parasympathetic ganglia scattered through the pelvic plexus on either side. Synonym: ganglia pelvina, hypogastric ganglia. (05 Mar 2000) |
| ganglia phrenica | Several small autonomic ganglia contained in the plexuses accompanying the inferior phrenic arteries. Synonym: ganglia phrenica. (05 Mar 2000) |
| ganglia plexuum autonomicorum | Autonomic ganglia lying in plexuses of autonomic fibres, e.g., the coeliac and inferior mesenteric ganglia of the sympathetic, and the small parasympathetic ganglia of the myenteric plexus. Synonym: ganglia plexuum autonomicorum. (05 Mar 2000) |
| ganglia renalia | Small scattered sympathetic ganglia along the renal plexus. Synonym: ganglia renalia. (05 Mar 2000) |
| ganglia sacralia | Three or four ganglia on either side constituting, with the ganglion impar and the interganglionic rami, the pelvic portion of the sympathetic trunk. Synonym: ganglia sacralia. (05 Mar 2000) |
| ganglia, sensory | Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. Sensory ganglia may also have intrinsic interneurons and non-neuronal supporting cells. (12 Dec 1998) |
| ganglia, spinal | Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain. (12 Dec 1998) |
| ganglia, sympathetic | Ganglia of the sympathetic nervous system including the paravertebral and the prevertebral ganglia. Among these are the sympathetic chain ganglia, the superior, middle, and inferior cervical ganglia, and the aorticorenal, coeliac, and stellate ganglia. (12 Dec 1998) |
| ganglia thoracica | Ganglia, 11 or 12 on either side, at the level of the head of each rib, constituting with the interganglionic rami the thoracic portion of the sympathetic trunk. Synonym: ganglia thoracica. (05 Mar 2000) |
| ganglia trunci sympathici | The clusters of postganglionic neurons located at intervals along the sympathetic trunks, including the superior cervical, middle cervical, and cervicothoracic (stellate) ganglion, the thoracic, lumbar, and sacral ganglia, and the ganglion impar. Synonym: ganglia trunci sympathici, paravertebral ganglia. (05 Mar 2000) |
| parasympathetic ganglia | Those ganglia of the autonomic nervous system composed of cholinergic neurons receiving afferent fibres from preganglionic visceral motor neurons in either the brainstem or the middle sacral spinal segments (S2 to S4); on the basis of their location with respect to the organs they innervate, most parasympathetic ganglia, at least outside the head, can be categorised as juxtamural or intramural ganglia. See: autonomic nervous system. (05 Mar 2000) |
| paravertebral ganglia | The clusters of postganglionic neurons located at intervals along the sympathetic trunks, including the superior cervical, middle cervical, and cervicothoracic (stellate) ganglion, the thoracic, lumbar, and sacral ganglia, and the ganglion impar. Synonym: ganglia trunci sympathici, paravertebral ganglia. (05 Mar 2000) |
| Vieussens' ganglia | The largest and highest group of prevertebral sympathetic ganglia, located on the superior part of the abdominal aorta, on either side of the origin of the coeliac artery; contains sympathetic neurons whose unmyelinated postganglionic axons innervate the stomach, liver, gallbladder, spleen, kidney, small intestine, and ascending and transverse colon. H Synonym: ganglia coeliaca, semilunar ganglion, solar ganglia, Vieussens' ganglia, Willis' centrum nervosum. (05 Mar 2000) |
