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.
Stimulus from different sources may increase or decrease this membrane potential for a brief period of time, before the membrane potential returns back to it's normal resting level. This transient change of membrane potential is known as graded potential. The size and duration of these graded potentials are dependent on the size and duration of both excitatory and inhibitory impulses.
