NO NEED FOR FULL PARAGRAPHS JUST A QUICK LITTLE IDEA ABOUT E

NO NEED FOR FULL PARAGRAPHS, JUST A QUICK LITTLE IDEA ABOUT EACH.

Label #1-3 and tell me what those terms mean in terms change in membrane potential.

Solution

1 . De polarisation

Membrain potential spikes up from -55mv to +60 mv due to opening of sodium channels

2. Repolarisation

Membrane potential decreases to approx -85 mv due to outflux of potassium ions.

3. Hyperpolatisation

Membrane potential further reduces its potential before a refractory phase can be reached
