Question

Which one of the following statements about the autonomic nervous system is INCORRECT?

A) Sympathetic post-ganglionic neurons release noradrenaline as the neurotransmitter

B) Parasympathetic post-ganlionic neurons release noradrenaline as the neurotransmitter

C) Sympathetic pre-ganglionic neurons release acetylcholine as the neurotransmitter

Answer 1

Answer

Option B) Parasympathetic post-ganlionic neurons release noradrenaline as the neurotransmitter

• In parasympathetic nervous system, post-ganglionic neurons are cholinergic and release acetylcholine as neurotransmitter.
• Parasympathetic nervous system facilitates activity of rest and digest.
• In sympathetic nervous system, preganglion neurons release acetylcholine and postganglionic neurons release noradrenalin (norepinephrine).

Hence, the above statement is INCORRECT.
