WebThe initial changes are called receptor potentials, and they are produced by the movement of positively charged ions (e.g., sodium ions) into the cell through openings in the cell membrane called ion channels. Thus, in order to stimulate a receptor cell, a chemical must cause particular ion channels to be… Read More nervous systems WebFor an action potential to be generated, the stimulus must be strong enough to bring the membrane voltage to a critical value that is the threshold which is about -55 millivolts. This is also the minimum voltage that is required to open the voltage-gated channels. Once this voltage is achieved, an action potential is generated.
