Definitions:

Resting Potential

Electrical charge across the insulating cell membrane in the absence of stimulation; a store of potential energy produced by a greater negative charge on the intracellular side relative to the extracellular side.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative and decreasing the likelihood of generating an action potential.

Semipermeable Membrane

A barrier that allows certain molecules or ions to pass through it by diffusion while blocking others, often used in osmosis.

Sodium-Potassium Pump

A type of active transport mechanism that moves sodium ions out of and potassium ions into cells, essential for maintaining cell potential and volume.
