It is generally known that when the surface of a cell is injured, one is able to measure a potential difference between the site of injury and the intact surface of that cell. The P.D. observed in such instances are of the order of 50-90 mv. The injury is believed to serve as the point of electrical connection between the inside and the outside of the cell, and that the potential exists across the plasma membrance or boundary of the cell.
