Solution

The correct sequence of the events can be put up in the given table as follows:

Rising Phase

Falling Phase

After-hyperpolarization

1. In the rising phase, the voltage-gated Na+ channels open. This leads to the influx of the Na⁺ ions into the axon and the membrane potential, therefore, becomes positive.

2. In the falling phase, the voltage-gated K⁺ channels open and the ions move out of the axon. The Na⁺ channels are closed.

3. In the after-hyperpolarization phase, the K⁺ voltage-gated channels are still open and some of the ions still move out of the axon.

Rising Phase	Falling Phase	After-hyperpolarization
The opening of voltage-gated Na+ (sodium) channels. Na+ ions move into the axon. Membrane potential becomes positive.	Voltage-gated K+ (potassium) channels open. K+ ions move out of the axon. Voltage-gated Na+ channels close.	Some voltage-gated channels still open. K+ continues to move out of the axon.
