A motor neuron that forms a synapse with one or more preganglionic motor neurons, is located outside the central nervous system, and has its unmyelinated axon ending in smooth muscle, cardiac muscle, or a gland. ganglionic motor neuron peripheral motor neuron.


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).

The following schematic image shows locations of a number of autonomic ganglia (yellow ovals) in the periphery. A bilateral chain of paravertebral ganglia is located beside vertebral bodies in thoracic and abdominal cavities. 2020-11-19 Synonyms for postganglionic n in Free Thesaurus.

The postganglionic neuron will then cross a synapse at the target organ. 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: A nerve cell that is located distal or posterior to a ganglion. In the autonomic nervous system, fibers from the ganglion to the effector organ are called postganglionic fibers. What are postganglionic neurons? Neurons The nervous system (NS) is a crucial way in which the body relays and communicates signals to different regions of the body in a matter of milliseconds.
