All preganglionic autonomic fibers release acetylcholine (ACh) at their synaptic terminals. The effects are always stimulatory. Postganglionic parasympathetic fibers also release ACh, but the effects may be either stimulatory or inhibitory, depending on the nature of the receptor. Most postganglionic sympathetic terminals release the neurotransmitter norepinephrine (NE). The effects are usually stimulatory.
