1. When membrane potential changes, we use the terms depolarization, hyperpolarization, and repolarization. Explain what is happening to the membrane potential in relation to the extracellular fluid during depolarization and hyperpolarization. Explain how depolarization is possible with the movement of positive ions. Explain how depolarization is possible with the movement of negative ions. Explain how hyperpolarization is possible with the movement of both positive and negative ions, like you did for depolarization.
