Correct Answer: B
Solution :
[b] The presynaptic membrane is first depolarised, stimulating the release of acetylcholine, the transmitter substance. This diffuses to the postsynaptic membrane, propagating the nervous stimulus. Acetylcholine is then hydrolysed.You need to login to perform this action.
