Does parasympathetic have postganglionic axons secrete norepinephrine?

No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.


The postganglionic receptors for the pns are muscarine?

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.


Are parasympathetic postganglionic fibers generally come from adrenergic fibers?

No, parasympathetic postganglionic fibers do not come from adrenergic fibers. Parasympathetic postganglionic fibers release acetylcholine as their neurotransmitter, whereas adrenergic fibers release norepinephrine.
