Definitions:

Action Potential

A rapid, temporary change in a cell's membrane potential, allowing neurons to communicate through electrical signals.

Polarity

The property of having distinct and opposite ends or poles, used in various contexts such as electricity, magnetism, and molecular chemistry.

Membrane

A thin layer of tissue or material that acts as a boundary, separating different areas or substances, crucial in cellular function and structure.

Depolarization

The process by which a neuron's membrane potential becomes less negative, making the neuron more likely to fire an action potential.
