Vedclass · Answer

(A) Nerve impulses are transmitted across a synapse with the help of chemical substances known as neurotransmitters. In the human nervous system,the most common neurotransmitters involved in synaptic transmission are Acetylcholine and Noradrenaline (also known as Norepinephrine). While Adrenaline and Noradrenaline are catecholamines,Acetylcholine is a distinct ester neurotransmitter. Since the question asks for the substances involved in transmission,and considering standard textbook options,the most accurate representation of neurotransmitters involved in synaptic transmission is Acetylcholine and Noradrenaline. However,looking at the provided options,option $A$ mentions Sympathin (an older term for Noradrenaline). Therefore,the correct answer is $A$.
