Step 1 The threshold of excitation is reached and voltage-gated Na+ channels open. Na+ flows in.
Step 2 Once the cell becomes depolarized, this causes voltage-gated K+ channels to open and K+ leaks out.
Step 3 The voltage-gated Na+ channels become refractory.
Step 4 Voltage-gated K+ channels remain open and K+ continues to leave, hyperpolarizing the cell.
Step 5 Voltage-gated K+ channels close and the voltage-gated Na+ channels reset
Step 6 Extra K+ diffuses away.
