Definitions:

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.

Hyperpolarization

A change in a cell's membrane potential that makes it more negative, moving further away from zero, which decreases the likelihood of generating an action potential.

Sodium
