Hillock cells
WebAs covered in Chapter 1, the action potential is a very brief change in the electrical potential, which is the difference in charge between the inside and outside of the cell. During the action potential, the electrical potential across the membrane moves from a negative resting value to a positive value and back. Figure 6.1. WebThe meaning of HILLOCK is a small hill.
