In these ganglia, the axons of preganglionic neurons synapse on ganglionic neurons. The axons, or postganglionic fibers, of these neurons 

The neurotransmitters of postganglionic fibers differ: In the parasympathetic division, neurons are cholinergic. That is to say acetylcholine is the primary neurotransmitter responsible for the communication between neurons on the parasympathetic pathway. In the sympathetic division, neurons are mostly adrenergic (that is, epinephrine and norepinephrine function as the primary neurotransmitters). postganglionic neuron A neuron of the autonomic nervous system whose cell body lies in an autonomic ganglion and whose axon terminates in a visceral effector (smooth or cardiac muscle or glands).

Postganglionic neuron

of two neurons, a preganglionic neuron and a postganglionic neuron, in contrast to only a single neuron in the skeletal motor pathway. The cell body of each pregan-glionic neuron lies in the intermediolateral horn of the spinal cord ; its fiber passes, as shown in Figure 60-2, through an anterior root of the cord into the corresponding spinal nerve.

Sympathetic preganglionic fibers tend to be shorter than parasympathetic preganglionic fibers because sympathetic ganglia are often closer to the spinal cord while parasympathetic preganglionic fibers tend to project to and synapse with the postganglionic fiber close to the target organ. Postganglionic neurons release norepinephrine that binds to alpha adrenergic receptors and beta adrenergic receptors on the target organ, causing a sympathetic response. The postganglionic neurons of the sympathetic nervous system are called adrenergic neurons as they release norepinephrine.

It is concluded that synaptogenisis and onset of neurotransmission are causally associated with development of CNS regulation of postganglionic activity and end organ response rather than with maturation of the postganglionic neuron and that cholinergic excitation of the postganglionic neuron adequate to evoke action potentials is not essential to initiate maturation of the neuron.

While a few postganglionic endings of the sympathetic nervous system secrete acetylcholine, the majority of the sympathetic endings secrete norepinephrine. These fibers are said to be adrenergic. Since each preganglionic axon diverges to an average of 8-9 postganglionic neurons, autonomic output is widely diffused.

Like those in the superior cervical ganglion, most postganglionic neurons recorded from a lumbar sympathetic ganglion in the rat – the majority of which are vasoconstrictor in function – are driven by one “primary” preganglionic neuron, but inputs from two (or rarely three) “secondary” preganglionic neurons can occasionally contribute to the firing of a single postganglionic neuron (Bratton et al., 2010).
