Definitions:

Plasma Membrane

A biological barrier that demarcates the internal space of every cell from the external world, overseeing the transport of elements entering and exiting the cells.

Depolarization

A reduction in the difference in voltage across a cell's plasma membrane, making it more positive inside.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative, and often reducing the likelihood of producing a nerve impulse.

Repolarization

The process of restoring the resting negative charge inside a cell membrane after depolarization, crucial for the function of nerve and muscle cells.
