Membrane potential, also known as transmembrane potential or membrane voltage, refers to the difference in electrical potential between the interior and exterior of a cell, that is created due to the differences in concentration and movement of various ions across the membrane. The inside of a living cell is usually considered to be negative (voltage measured in millivolts or mV) and the exterior, positive. At a certain potential difference known as the resting potential, the cell membrane is relatively stable, with the inside more negative than outside.
