When a neuron is resting, it has a higher concentration of Na⁺ ions inside the cell membrane than outside.

Question

Quizplus · Accepted Answer

When a neuron is resting, it has a higher concentration of potassium ions (K+) inside the cell membrane and a higher concentration of sodium ions (Na+) outside the cell membrane. This is maintained by the sodium-potassium pump, which actively transports Na+ ions out of the cell and K+ ions into the cell.
