| TAB | total autonomic blockage; typhoid, paratyphoid A, and paratyphoid B [vaccine] |
| pulmonary branch of autonomic nervous system | Pulmonary branches of cardiac plexuses and cardiaopulmonary splanchnic nerves. Synonym: rami pulmonales systematis autonomici. (05 Mar 2000) |

| nervous system, autonomic | Part of the nervous system once thought functionally independent of the brain. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: (1) the sympathetic nervous system, which accelerates the heart rate, constricts blood vessels, and raises blood pressure; and (2) the parasympathetic nervous system, which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (12 Dec 1998) |
| neuropathies, hereditary sensory and autonomic | A group of inherited disorders in which there is selective involvement of the peripheral sensory and autonomic neurons and degeneration of fibres by axonal atrophy and degeneration. Five types of disorders have been described and classified type I through type v. (12 Dec 1998) |
| aorticorenal ganglia | A semidetached portion of the coeliac ganglia, at the origin of each renal artery; contains the sympathetic neurons innervating the vasculature of the kidney. Synonym: ganglia aorticorenalia. (05 Mar 2000) |
| Auerbach's ganglia | Collections of parasympathetic nerve cells in the myenteric plexus. See: myenteric plexus. (05 Mar 2000) |
| basal ganglia | <anatomy> Three large subcortical nuclei of the vertebrate brain: the putamen, the caudate nucleus and the globus pallidus. They participate in the control of movement along with the cerebellum, the corticospinal system and other descending motor systems. Lesions of the basal ganglia occur in a variety of motor disorders including Parkinson's disease and Huntingdon's chorea. (15 Nov 1997) |
| basal ganglia calcification | <radiology> Idiopathic: normal variant (50%), abnormal calcium metabolism, hyperparathyroidism, hypo-, pseudohypo-, and pseudo-pseudohypoparathyroidism, ToRCHS infection (especially CMV, toxo), tuberous sclerosis, Cockayne syndrome, Fahr syndrome (ferrocalcinosis), lipoid proteinosis (hyalinosis cutis) (12 Dec 1998) |
| cardiac ganglia | 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 | <pathology> A mass of nerve tissue (grey matter) or a group of nerve cell bodies. <anatomy> Also refers to specific groups within the brain or spinal cord (as basal ganglia). Ganglion is the singular of ganglia. (16 Dec 1997) |
| ganglia aorticorenalia | A semidetached portion of the coeliac ganglia, at the origin of each renal artery; contains the sympathetic neurons innervating the vasculature of the kidney. Synonym: ganglia aorticorenalia. (05 Mar 2000) |
| 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) |
