Diagram of neurone at rest.
- Sodium potasium pump - These pumps use active transport to move three sodium ions out of the neurone for every two potassium ions. - ATP is needed.
- Potassium ion channel - These channels allow facilitated diffusion of potassium ions out of the neurone, down their concentration gradient.
