| ganglia, autonomic | Clusters of neurons and their processes in the autonomic nervous system. In the autonomic ganglia, the preganglionic fibres from the central nervous system synapse onto the neurons whose axons are the postganglionic fibres innervating target organs. The ganglia also contain intrinsic neurons and supporting cells and preganglionic fibres passing through to other ganglia. (12 Dec 1998) |
|---|---|
| ganglia cardiaca | Parasympathetic ganglia of the cardiac plexus lying between the arch of the aorta and the bifurcation of the pulmonary artery. Synonym: ganglia cardiaca, Wrisberg's ganglia. (05 Mar 2000) |
| ganglia coeliaca | 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) |
| ganglia intermedia | Small sympathetic ganglia most commonly found on the communicating branches in the cervical and lumbar region. Synonym: ganglia intermedia. (05 Mar 2000) |
| ganglia, invertebrate | Clusters of neuronal cell bodies in invertebrates. Invertebrate ganglia may also contain neuronal processes and non-neuronal supporting cells. Many invertebrate ganglia are favourable subjects for research because they have small numbers of functional neuronal types which can be identified from one animal to another. (12 Dec 1998) |
| ganglia lumbalia | Four or more ganglia on the medial border of the psoas major muscle on either side; they form, with the sacral and coccygeal ganglia and their interganglionic rami, the abdominopelvic sympathetic trunk. Synonym: ganglia lumbalia. (05 Mar 2000) |
| ganglia of autonomic plexuses | 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 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) |
