For example, preganglionic neuron coming along with vagus nerve connects with a postganglionic fiber specific to heart. Note: Along with vagus nerve many preganglionic fibers emerge and can supply to various organs like heart, lungs and GIT but postganglionic neurons supplying to …
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. Structural unit of the nervous system consisting of the nerve cell body and its various processes, the dendrites, the axon and the ending (also called bouton, end foot or axon terminal). The first neuron carries the nerve impulse from the CNS to the ganglion and is called the preganglionic neuron.
Neurons are classified according to their position in a reflex arc: afferent, or sensory, neurons receive information from the external environment or from receptor cells; interneurons, or internuncial neurons, connect one neuron with another; efferent neurons transmit impulses to the organs of response (for example, motoneurons innervate muscles).

Most postganglionic nerves leave the chain as gray communicating rami to join the anterior divisions at C5-T1, nerves that form the brachial plexus. Some postganglionic nerves pass directly from the chain to form the subclavian perivascular plexus and innervate the subclavian, axillary, and upper part of the brachial arteries. 2

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).
-The axon is a small‐diameter, unmyelinated type C fiber that terminates in a visceral effector. All preganglionic neurons in both the sympathetic and parasympathetic arms of the ANS are cholinergic. In terms of postganglionic fibers: All parasympathetic postganglionic neurons are cholinergic; however, only a small minority of sympathetic postganglionic neurons are cholinergic (those innervating sweat glands) whereas the rest are adrenergic. The cell body for the parasympathetic postganglionic neuron is located in ganglia a Sympathetic Terminal c Collateral onto the end organ The sympathetic nervous system releases a Norepinephrine Acetylcholine Nicotine Dopamine Parasympathetic postganglionic neurons have what kind of receptors?

2021-04-02 · Increased sympathetic activation of postganglionic neurons innervating the kidneys would cause both decreased renal arterial flow and GFR by constriction of the efferent arteriole. This statement is completely false. This statement is completely true. The first part of this statement is true and the second is false.
These neurons regulate activity of most organs of the body by releasing combinations of neurotransmitters.
