At rest, the sodium-potassium pump expels sodium and accumulates potassium. When a neuron fires, these ions move across the membrane via facilitated diffusion through channels.
At rest, the sodium-potassium pump moves sodium ions out and potassium ions in. When a neuron fires, these ions swap locations via facilitated diffusion through specific ion channels.
