Definitions:

Resting Plasma Membrane

The state of the plasma membrane of a cell when it is not being excited by external stimuli, maintaining a specific voltage across it.

Positively Charged

Describes atoms or molecules that have more protons than electrons, resulting in a net positive electrical charge.

Electrically Neutral

A condition where an object or system has an equal number of positive and negative charges, leading to no net electrical charge.

Depolarization

A reversal in the electrical potential across a cell's plasma membrane, leading to the initiation of an action potential or nerve impulse.
