What Is Repolarization?
Repolarization is the process of generating and developing action potentials, which restores the potential from the reversed polarization state to the resting state of the positive potential outside the membrane and the negative potential inside the membrane. It is called repolarization. For example: the potential in the membrane gradually decreases from + 30mV to the resting potential level. Repolarization is caused by the outflow of potassium ions.

- Action potential and its generation mechanism Based on the resting potential, the excitable cell membrane receives a proper stimulation, and the membrane potential undergoes rapid transient fluctuations. This kind of membrane potential fluctuation is called action potential. Taking skeletal muscle cells as an example, it is composed of ascending and descending branches, and the potential changes that form spikes are called spikes. The rising intra-membrane potential from the resting potential of -90mV to + 30mV, which rises from -90mV to 0mV, is called depolarization; from 0mV to + 30mV, that is, the membrane potential becomes internal positive and negative, called Reverse polarization. A potential value with an action potential above zero is called overshoot. The falling intramedullary potential gradually decreases from + 30mV to the resting potential level, which is called repolarization.
