Question

Quizplus · Accepted Answer

Activation of muscarinic acetylcholine (ACh) receptors leads to the closing of M-channels, which are a type of potassium channel. When these channels close, the efflux (outward flow) of potassium is reduced, making the inside of the cell more positive and closer to the threshold for firing an action potential. This mechanism is part of how acetylcholine can modulate neuronal activity through muscarinic receptors.
