Repolarization occurs when sodium channels close and potassium channels open, allowing potassium efflux and return to resting potential.
Repolarization occurs as sodium channels close and potassium channels open, allowing potassium ions to diffuse out, returning the membrane to its resting potential.
| Front | Repolarisation (action potential formation) |
|---|---|
| Back | At potential difference of +30mV sodium ion channels close Potassium ion channels open Membrane more permeable to potassium Potassium ions diffuse out down potassium ion conncentation gradient Membrane back to resting potential |
