Join the Amoeba Sisters as they explore the action potential. This video discusses resting membrane potential before going into the phases of the action potential including vocabulary such as depolarization, repolarization, and hyperpolarization. The video also mentions different types of gated ion channels and how the action potential can be propagated.
