Resting potential action potential
WebBefore examining the ionic mechanisms of action potentials, it is first necessary to understand the ionic mechanisms of the resting potential. The two phenomena are … WebResting potential. The resting potential describes the unstimulated, polarized state of a neuron (at about –70 millivolts). Graded potential. A graded potential is a change in the resting potential of the plasma membrane in the response to a stimulus. A graded potential occurs when the stimulus causes Na + or K + gated
