where is acetylcholine released in the sympathetic nervous system
Acetylcholine
At a schematic level , the sympathetic and parasympathetic nervous systems are both organized in essentially the same way : preganglionic neurons in the central nervous system send projections to neurons located in autonomic ganglia ; these neurons then send output projections to virtually every tissue of the body . In both branches the internal connections -- the projections from the central nervous system to the autonomic ganglia -- use acetylcholine as neurotransmitter , and the receptors it activates are of the nicotinic type . In the parasympathetic nervous system the output connections -- the projections from ganglion neurons to tissues that do n't belong to the nervous system -- also release acetylcholine , acting on muscarinic receptors . In the sympathetic nervous system the output connections mainly release noradrenaline , although acetylcholine is released at a few points , such as the sudomotor innervation of the sweat glands .
