An action potential is best defined as _______.

Question

Quizplus · Accepted Answer

An action potential is a brief, electrical signal within a neuron caused by the movement of ions across the neuron's membrane. It involves the opening and closing of ion channels, specifically, the opening of voltage-gated sodium channels, which leads to depolarization and the generation of an action potential, and the subsequent closing of these channels and opening of voltage-gated potassium channels, which leads to repolarization and the restoration of the resting membrane potential.
