The sympathetic nervous system is one of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. Most sympathetic neurons, but not all, use noradrenaline as a post-ganglionic neurotransmitter [GO].
Comment:
[development-note] "has developmental contribution from NC in verteberates (https://github.com/obophenotype/uberon/wiki/The-neural-crest)"; [homology-note] "The autonomic nervous system is composed of three divisions: the sympathetic division, the parasympathetic division, and the enteric division. (...) In ray-finned teleost fishes, a sympathetic chain is present, and dual innervation of additional organs can be observed. A similar pattern can be found in amphibians (...). The evolution of the autonomic nervous system has been quite conservative, especially in the tetrapod lineage.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000384", ontology="VHOG", source="ISBN:978-0471210054 Butler AB and Hodos W, Comparative vertebrate neuroanatomy: Evolution and Adaptation (2005) p.461-463", source="http://bgee.unil.ch/"}
