Question

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

Resting potential... is the state in which a neuron is at rest, with a relatively negative membrane potential and no action potential occurring

Threshold potential... is the potential where an action potential can be initiated

Depolarization... is the process by which the membrane potential of a neuron becomes more positive

Repolarization.... is the process by which the membrane potential of a neuron becomes more negative back to its resting state
