Definitions:

Action Potential

A temporary reversal of the electrical polarization of the membrane of a nerve cell or muscle cell, primarily involved in the transmission of nerve impulses.

Hyperpolarization

A change in a cell's membrane potential that makes it more negative, moving it further from the threshold for electrical activity.

Membrane Potential

The difference in electric potential between the inside and outside of a cell's plasma membrane, crucial for the transmission of nerve impulses.

Potassium Gates

Channels in the cell membrane that allow potassium ions to move in and out, influencing cellular activity and electrical charge.
