Explanation:
Detailed explanation-1: -The resting potential of the average neuron is around-70 millivolts, indicating that the inside of the cell is 70 millivolts less than the outside of the cell. At this point, the brain has not yet sent the message to the hand to pick up the glass, but the neuron is ready to receive the signal.
Detailed explanation-2: -Depolarization is caused by a rapid rise in membrane potential opening of sodium channels in the cellular membrane, resulting in a large influx of sodium ions. Membrane Repolarization results from rapid sodium channel inactivation as well as a large efflux of potassium ions resulting from activated potassium channels.
