After an action potential, the opening of voltage-gated potassium channels and Na channels causes the membrane to return to its resting membrane potential.
What is an action potential?
An action potential is defined as a difference in electrical charges across the cell membrane due to the unequal distribution of ions.
An action potential is produced by potassium and sodium channels that allow the movement of positive ions across the membrane.
In conclusion, after an action potential, the opening of voltage-gated potassium channels and Na channels causes the membrane to return to its resting membrane potential.
