The size of the action potential is independent of stimulus magnitude. This is referred to as the _______ property of action potentials.
A) ionic
B) resting
C) all-or-none
D) threshold

Question

Quizplus · Accepted Answer

The all-or-none property of action potentials means that either a full action potential is produced or none at all, regardless of the strength of the stimulus. This is due to the fact that once the threshold for firing an action potential is reached, there is a rapid and complete depolarization of the membrane, leading to the characteristic shape and size of the action potential.
