Postganglionic neuron -lies entirely outside the CNS in the PNS. -Its cell body and dendrites are located in an autonomic ganglion, where it forms synapses with one or more preganglionic axons. -The axon is a small‐diameter, unmyelinated type C fiber that terminates in a visceral effector. The postganglionic neuron will then cross a synapse at the target organ. 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 innervating the hind paw plantar skin before the capsaicin injection prevented secondary hyperalgesia.

Also note that, at each level, the axons of the postganglionic neurons in the paravertebral ganglia re-enter the corresponding spinal nerves through gray rami​,  The sympathetic preganglionic neurons are found in the intermediolateral gray matter of the spinal cord. Postganglionic neurons are located to the sympathetic  (2) it augments the release of acetylcholine from intrinsic cholinergic neurons It also inhibits the action of acetylcholine at the postganglionic nerve endings  Nerve endings of the parasympathetic post-ganglionic neurons secret aceylcholine.

(In contrast, somatic efferent (SE) innervation of skeletal muscle involves only a single neuron; its cell body in the CNS.) Autonomic postganglionic neurons release either acetycholine (ACh) or nor-epinephrine (NE), the former neurons are designated cholinergic, the latter adrenergic. All parasympathetic postganglionic neurons are cholinergic. The great majority of sympathetic postganglionic neurons are adrenergic (except that neurons innervating sweat glands In this protocol, we describe a stable, highly efficient differentiation strategy for the generation of postganglionic sympathetic neurons from human pluripotent stem cells. This model will make neurons available for the use of studies of multiple autonomic disorders. Die postganglionären Neuronen des sympathischen Systems sind androgen.

Department of Aizutonzy, Cornell University Medical College,  The parasympathetic system only has a preganglionic neuron, which uses Parasympathetic postganglionic neurons are found closer to the effector than  In response to this stimulus, postganglionic neurons principally release noradrenaline (norepinephrine). Prolonged activation can elicit the release of adrenaline  Postganglionic neurons are a group of neurons that present in ANS connecting ganglia to effector organ. This is the key difference.
