1. When the cell membrane is at its resting membrane potential, in what position are the voltage-gated sodium and potassium channels?
2. Is initiated by a stimulus that makes the membrane.
3. What affect does this have on the voltage-gated sodium channels? What occurs at threshold?
4. What causes depolarization? What happens to the voltage-gated potassium channels?
5. Therefore, depolarization occurs because.
6. What causes the diffusion of sodium ions to decrease? What happens to the potassium ions?
7. What causes the membrane potential to become slightly more negative than the resting value?
8. What causes reestablishment of resting membrane potential?
