4) A graded potential is just the slight difference in charge across the membrane of a cell. If more negatively charged ions like potassium and sodium go across to the interior of the membrane than the inside charge becomes more negative.
The magnitude of the change of the membrane potential in a graded potential is dependent upon the strength of the stimulus. The larger stimulus, the greater change in potential. Graded potentials are not the nerve signals that travel along an axon, but do influence their generation. If depolarization occurs, then voltage-gated ion channels open and develop an action potential. Actions potentials are the nerve impulses that occur when the membrane voltage reaches a certain value, known as the threshold.
