Definitions:

Potential Difference

Difference in electrical potential, measured as the charge difference across the plasma membrane.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative and less likely to fire an action potential.

Voltage-Gated

Pertaining to ion channels that open or close in response to changes in membrane potential, crucial for nerve impulse conduction.

Na+

Na+ represents Sodium ions, which are essential electrolytes in the body that help maintain blood pressure, fluid balance, and are critical for the functioning of muscles and nerves.
