The following are the main steps in the generation of an action potential: 1. Sodium channels are inactivated.2. Voltage-gated potassium channels open and potassium moves out of the cell, initiating repolarization.3. Sodium channels regain their normal properties.4. A graded depolarization brings an area of an excitable membrane (the axon hillock) to threshold.5. A temporary hyperpolarization occurs.6. Voltage-gated sodium channels are activated and open.7. Sodium ions enter the cell and depolarization occurs. What is the proper sequence of these events?
