The common neurotransmitter of peripheral nervous system
The common neurotransmitter of peripheral nervous system
Open in App
Solution
The correct option is B Acetylcholine
Peripheral nervous system is divided into somatic and
autonomic nervous system. The autonomic nervous system is further categorised
as sympathetic and parasympathetic nervous system. Acetylcholine is the neurotransmitter
secreted by both pre- and post-ganglionic parasympathetic neurons while
epinephrine/nor epinephrine is released by sympathetic postganglionic neurons
(the adrenergic neurons). The sympathetic preganglionic neurons release
acetylcholine. This makes acetylcholine a common neurotransmitter of PNS. Thus,
option B is correct and options A and C incorrect. GABA is the inhibitory neurotransmitter
that reduces the activity of neurons in brain upon binding.
