The opposite of postganglionic is preganglionic. Preganglionic neurons are responsible for carrying nerve impulses from the central nervous system to ganglia, while postganglionic neurons transmit nerve impulses from ganglia to target organs.
The postganglionic sympathetic fiber originates from PNS within a ganglion
Sympathetic nervous system, which is part of autonomic nervous system.
Preganglionic sympathetic fibers trigger the release of acetylcholine at the synapse with postganglionic neurons in the sympathetic ganglia. This neurotransmitter binds to nicotinic acetylcholine receptors on the postganglionic neuron, which then propagate the signal to release norepinephrine at the target tissue.
Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within the sympathetic chain ganglia (paravertebral ganglia) or prevertebral ganglia (e.g., celiac ganglion). These ganglia are part of the sympathetic division of the autonomic nervous system and play a role in coordinating the body's fight-or-flight responses.
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
Actually, the postganglionic receptors for the parasympathetic nervous system (PNS) are predominantly muscarinic receptors. These receptors are activated by acetylcholine released from postganglionic parasympathetic nerve terminals.
No, parasympathetic postganglionic fibers do not come from adrenergic fibers. Parasympathetic postganglionic fibers release acetylcholine as their neurotransmitter, whereas adrenergic fibers release norepinephrine.

The submandibular ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands.
The renal plexus is the sympathetic ganglion that distributes postganglionic neuronal processes to the kidneys.

The parasympathetic nervous system has long preganglionic and short postganglionic fibers
