Repolarization

A) Small change in the resting membrane potential confined to a small area
B) Charge difference across the plasma membrane when the cell is in an unstimulated state
C) Larger change in resting membrane potential that spreads over entire surface of a cell
D) Membrane becomes more positive when Na⁺ diffuse into cell
E) Return to the resting membrane potential

Repolarization

The process by which a cell's membrane potential returns to its resting state following depolarization.

Resting Membrane Potential

The electric potential difference across the membrane of a resting (non-active) cell, essential for the transmission of nerve impulses.

Plasma Membrane

The semipermeable membrane surrounding the cytoplasm of a cell, which regulates the movement of substances in and out of the cell.
