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

Neurotransmitters

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.

* Preganglionic fibers
