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]. sympathetic nervous system UBERON:0000013 sympathetic nervous system MIAA:0000100 EHDAA2:0001971 UMLS:C0039044 AAO:0010487 EMAPA:16985 BTO:0001832 MA:0000225 NCIT:C12795 VHOG:0000384 EFO:0000893 FMA:9906 GAID:710 autonomic nervous system organ system subdivision
