sympathetic nervous system
The sympathetic preganglionic neurones 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 neurones, but not all, use noradrenaline as a post ganglionic neurotransmitter.
