I'm no doctor but...
"pre" beans before.
and "post" means after.
I know that ganglia are a bunch of nerve cells following a common route through a body to provide a shared function.
This is just gesswork but...
look for age-related scarring indicators in comparitive tissue (biopsy) samples.
Extreme care should be taken depending on the locus of the suspected trauma.

Are nerve fibers in ascending tracts myelinated?
If I was paying attention in med school, I think... The pre-ganglionic fibers are myelinated and the post-ganglionic are unmyelinated. This is in reference to the sympathetic and parasympathetic systems.
What is the fate of the neutotransmitter after its release from the vesicles in the presynaptic neuron?
Noradrenaline or nor-epinephrine released in post ganglionic sympathetic nerve endings is taken up back by the nerves producing it. While acetyl choline secreted by preganglionic nerves and post ganglionic parasympathetic fibres are destroyed by the enzyme acetylcholinesterase, in milliseconds.
What is pre and post ganglionic?
Pre-ganglionic and post-ganglionic refer to the neurons in the autonomic nervous system. Pre-ganglionic neurons originate in the central nervous system (CNS) and project to autonomic ganglia, where they synapse with post-ganglionic neurons. The post-ganglionic neurons then extend to target organs, influencing functions such as heart rate, digestion, and respiratory rate. This two-neuron pathway is essential for the regulation of involuntary body functions.
Which division as short pre ganglionic axon and long post ganglionic axon?
sympathetic division
Which nerves release acetylcholine and adrenaline?
ALL pre- and post-ganglionic parasympathetic nerve cells PRE-ganglionic sympathetic nerve cells POST-ganglionic sympathetic nerve cells to sweat glands ONLY
What is neurotransmitter of the sympathetic nervous system?
acytelcholine in pre-ganglionic neurons, norepinephrine in most post-ganglionic neurons.
Which release norepinephrine?
The answer is sympathetic post-ganglionic axon
What is m-cholinomimetics?
they stimulate the action of ACh at post ganglionic muscarinic receptors.
Do the post-ganglionic sympathetic fibers release acetylcholine?
No, post-ganglionic sympathetic fibers mostly release norepinephrine. But they do release some ACh to the sweat glands, which causes concurrent vasodilation of surrounding blood vessels (paired with release of bradykinin from sweat glands).
Which neuro transmitter released from ganglionic of the parasympathetic division?
Nor-adrenaline is secreted at post ganglionic sympathetic synapses. There is re-uptake of Nor-adrenaline by nerve ending and only partially destroyed there by the enzyme C.O.M.T. There is no enzyme like acetylcholinesterase present there as in post ganglionic parasympathetic synapse to destroy the acetylcholine.
Does post ganglionic fibers release epinephrine?
No, postganglionic fibers release norepinephrine, not epinephrine. Epinephrine is released by the adrenal medulla.
Two major neurotransmitters of the autonomic nervous system?
You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
