Place the following generation of action potential steps in order:
1) sodium channels are inactivated.
2) voltage-regulated 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 excitable membrane to the threshold.
5) a temporary hyperpolarization occurs.
6) sodium channel activation occurs.7) sodium ions enter the cell and further depolarization occurs.
