Question

WILL MEDAL- Describe how the following stages occur in a neuron in terms of ion movement across the cell membrane: resting potential, threshold potential, depolarization, repolarization.

Answer 1

The steps go:
Depolarization, threshold potential, resting potential, and repolarization.
Hope this helps.

Answer 2

we have two surfaces of nerve cell the outer and inner surface resting : when the outer layer ion charge more positively than the inner layer deplarization : we have the counter part of this state repolarization : retun to the polarization hyperpolarization : the inner negative ion charges will be more negtive even more than the resting potential
