Membrane Potential

The difference in electric potential between the inside and outside of a cell's plasma membrane, crucial for the transmission of nerve impulses.

Potassium Gates

Channels in the cell membrane that allow potassium ions to move in and out, influencing cellular activity and electrical charge.

Sodium Gates

Protein channels in cell membranes that open or close in response to signals, allowing sodium ions to pass into or out of the cell.
