Explanation:
Detailed explanation-1: -An action potential can be further broken down into its separate stages: depolarization, repolarization, hyperpolarization, and the refractory period.
Detailed explanation-2: -The action potential can be divided into five phases: the resting potential, threshold, the rising phase, the falling phase, and the recovery phase. We begin with the resting potential, which is the membrane potential of a neuron at rest.
