Definitions:

Membrane Potential

The electrical potential difference across a cell's membrane, which affects the movement of ions and the activity of the cell.

Voltage-Gated

Pertaining to channels on cell membranes that open or close in response to changes in electrical membrane potential.

Neural Signaling

The process by which neurons communicate with each other through electrical and chemical signals to process and transmit information.

Effectors

Molecules, cells, or organs that act in response to signals, often involved in processes such as muscle contraction or gland secretion.
