ANATOMY

Detailed explanation-1: -In neuroscience, repolarization refers to the change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential which has changed the membrane potential to a positive value.

Detailed explanation-2: -The return of the membrane potential to the resting potential is called the repolarization phase.

Detailed explanation-3: -As an action potential travels down the axon, there is a change in polarity across the membrane. Repolarization occurs when the K+ channels open and K+ moves out of the axon. This creates a change in polarity between the outside of the cell and the inside.

Detailed explanation-4: -When the inside of the plasma membrane has a negative charge compared to the outside, the neuron is said to be polarized. Any change in membrane potential tending to make the inside even more negative is called hyperpolarization, while any change tending to make it less negative is called depolarization.
