A cell membrane normally is maintained at a resting potential of -70mV. When the receptors detect a stimulus, the membrane will generate an action potential to transmit the signal to the brain/spinal cord. In this video, we will look at the mechanisms of how the resting potential is maintained and re-established, and what happens to the membrane for an action potential to be generated.
