Question

Quizplus · Accepted Answer

Graded potentials are local changes in membrane potential that serve as short-distance signals. They can be either depolarizations or hyperpolarizations, and their amplitude varies directly with the strength of the stimulus that initiates them. Graded potentials do not typically result in an action potential but can trigger one if they reach a certain threshold.
