At the effector organs, sympathetic ganglionic neurons release [[noradrenaline]] (norepinephrine), along with other [[cotransmitters]] such as [[adenosine triphosphate|ATP]], to act on [[adrenergic receptors]], with the exception of the [[Sudomotor|sweat glands]] and the adrenal medulla:
* [[Acetylcholine]] is the preganglionic neurotransmitter for both divisions of the ANS, as well as the postganglionic neurotransmitter of parasympathetic neurons.  Nerves that release acetylcholine are said to be cholinergic.  In the parasympathetic system, ganglionic neurons use acetylcholine as a neurotransmitter to stimulate muscarinic receptors.
* At the [[adrenal medulla]], there is no postsynaptic neuron. Instead, the presynaptic neuron releases acetylcholine to act on [[nicotinic receptors]]. Stimulation of the adrenal medulla releases [[adrenaline]] (epinephrine) into the bloodstream, which acts on adrenoceptors, thereby indirectly mediating or mimicking sympathetic activity.
