Definitions:

Electrically Excitable Cells

Cells that can change their membrane potential in response to a stimulus, leading to generation and propagation of action potentials.

Depolarization

A reduction in the difference in electrical charge across a cell's plasma membrane, which is a crucial step in the conduction of impulses along nerve cells.

Voltage-Gated

Ion channels that open or close in response to changes in membrane potential, playing key roles in the transmission of neural impulses.

Myelin Sheaths

Protective coverings around nerve fibers made of myelin, which increase the speed at which impulses propagate along the myelinated fiber.
