Question

Explain in brief...
what is depolarization, depolarisation and repolarization(in context of nerve impulses) ? please no spam and do not copy from Google. ​

Answer 1

1. polarization is a resting potential. that is, there is no Nerve impulse passing through it and the sodium is outside and potassium is inside
2. depolarization is when the Nerve impulse passes through it and sodium moves in through the sodium channel and potassium moves out
3. repolarization occurs when the Nerve impulse finishes passing through it and here sodium and potassium comes back to its original position
