Main article: Autonomic ganglia

In the autonomic nervous system, fibers from the ganglion to the effector organ are called postganglionic fibers.

NeurotransmittersEdit

The neurotransmitters used for postganglionic fibers differ:

• In the parasympathetic division, they are cholinergic (that is, they use acetylcholine as their neurotransmitters.)

• In the sympathetic division, most are adrenergic (that is, they use norepinephrine as their neurotransmitters.) One exception of this is the sympathetic innervation of sweat glands, which uses acetylcholine as a neurotransmitter, at both pre and post ganglionic synapses.
