Definitions:

Plasma Membrane

The semipermeable membrane surrounding the cytoplasm of a cell, which regulates the movement of substances in and out of the cell.

Membrane Potential

The voltage difference across a cell's plasma membrane, crucial for the conduction of electrical signals in nerve and muscle cells.

Threshold

The minimum level of stimulus intensity required to activate a neuron or to trigger a physiological response.

Depolarization

A process in neurons and muscle cells where the membrane potential becomes less negative, leading towards an action potential.
