1. At location C, the membrane potential changes sign (from a positive value to a negative value) and the voltage-gated K+ channels are open. (This is repolarization, the neuron is returning to resting state.

2.At location F, the axon membrane reaches threshold and the voltage-gated Na+ channels open.

(This is depolarization and if the stimulus is up to threshold gives action potential)

3. At location A, the voltage-gated Na+ channels reactivate.(the cell is preparing for depolarization)

4. At location D the voltage-gated Na+ channels are inactivating and the voltage-gated K+ channels are opening.(this mark the end of depolarization, and the cell is returning to the resting state marking the beginning of repolarization)

5. At location G, the axon membrane is at resting potential. (The sodium and potassium voltage gated channels closed. The potassium channels leaks, sodium channels closed; the inner of the neuronal cell is negative in respect to the outside potassium channel)  

6. At location B the voltage-gated K+ channels are closing ( the cells is about to begin depolarization by opening of sodium-gated channels open,

7.  At location E, the membrane potential changes sign (from a negative value to a positive value) and the voltage-gated Na+ channels are open.  Depolarization commenced,
