Action potential ,the change in electrical potential associated with the passage of an impulse along the membrane of exciting cell. The order of steps in generation of action potential is-4.A graded depolarization brings an area of an excitable membrane to threshold.→ 6. in excitable membrane ,after that, Sodium channel get activated,→ 7. aftre that Sodium ions enter the cell and depolarization occurs,→1.after that, then 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,→ 5A temporary hyperpolarization occurs.
