Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
After depolarization repolarization occur whcih then again lead to resting potentiol
After the falling phase or repolarization the membrane potential goes below its normal resting potential.This phase is often called undershoot, or phase of hyperpolarization.
Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV.
Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV.

Repolarization is after depolarization. It descends to a region of hyper polarization where it is more polar than resting membrane potential

The Sodium Potassium Pump (opposed to the channels)
repolarization
Action Potential
repolarization
During resting potential, the Sodium-Potassium pump is inactive. Therefore, it is indirectly responsible for the resting potential. However, Potassium diffuses outside the membrane via "leakage" channels, and causes the resting potential.
