Diagram of preganglionic and postganglionic sympathetic and parasympathetic fibers (Reproduced with permission from Klauber RE, Cardiovascular Solid lines = preganglionic fibers, dotted lines = postganglionic fibers. T = thoracic spinal segment; IML = intermediolateral cell column. Gastrointestinal Tract. In the parasympathetic pathway, both the preganglionic and postganglionic axons release acetylcholine (ACh). In the sympathetic pathways, all preganglionic Autonomic nervous system (ANS) has ganglia. these ganglia are sites at which preganglionic fibers form synaptic connections with postganglionic neurons; these 4 Jun 2016 In contrast to the sympathetic system, the preganglionic parasympathetic neurons are generally longer than the postganglionic neurons as they 5 Mar 2018 From the ganglia, LONG postganglionic fibers run all the way to target organs.
The neurotransmitters of postganglionic fibers differ: In the parasympathetic division, neurons are cholinergic. That is to say acetylcholine is the primary neurotransmitter In the sympathetic division, neurons are mostly adrenergic (that is, epinephrine and norepinephrine function as the In

The postganglionic neurons exit the parasympathetic ganglion and extend all of the way to the target cell. The vagus nerve and the nerves that arise from the
The parasympathetic nerves use acetylcholine as the neurotransmitter for both the preganglionic and postganglionic nerves. The postganglionic parasympathetic fibers then project to the smooth muscle of the iris to control pupillary size. In the upper medulla, the salivatory nuclei contain neurons with axons that project through the facial and glossopharyngeal nerves to ganglia that control salivary glands. The ANS is unique in that it requires a sequential two-neuron efferent pathway; the preganglionic neuron must first cross a synapse onto a postganglionic neuron before innervating the target organ. The preganglionic, or first neuron will begin at the outflow and will cross a synapse at the postganglionic, or second neuron’s cell body. Carbachol was injected to activate nicotinic receptors on postganglionic parasympathetic nerves (i.e., intracardiac ganglion cells).

The neurotransmitter released by these postganglionic fibers at the target tissue is also ACh and it binds to muscarinic receptors. Sympathetic nerves that originate
Tonic pupil syndrome is a disorder secondary to lesion to the parasympathetic pathway at the ganglionic or postganglionic level.1 Manifestations include
The first neuron is called the preganglionic neuron, and the second is the postganglionic neuron.

The post-ganglionic fibers are short in case of the parasympathetic system because the ganglia are present near the target organs.

Peripheral postganglionic sympathicoplegia mimicking cluster headache suggest the importance of sympathetic/parasympathetic balance.
Both sympathetic and parasympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine (Ach) at the synapse in the ganglion. In the parasympathetic system, postganglionic neurons are also cholinergic. However in the sympathetic system, postganglionic are not all the same. Definition of parasympathetic fibers, postganglionic in the Definitions.net dictionary.

The postganglionic parasympathetic fibers also release ACh, but the receptors on their targets are muscarinic receptors, which are G protein–coupled receptors and do not exclusively cause depolarization of the postsynaptic membrane.
The presynaptic neurons of the parasympathetic system are located within the medulla oblongata and sacral spinal cord. The main neurotransmitter in both the sympathetic and parasympathetic nervous systems at the preganglionic fiber, as it contacts the postganglionic fiber is acetylcholine. The same is also true of the postganglionic fiber as it contacts the effector organ generally. Therefore, where acetylcholine is secreted, it is referred to as cholinergic. Postganglionic parasympathetic nerve fibers to the eye fire at 0.1 to 20 Hz at rest and at greater than 30 Hz during maximal activation.
