- Synopsis
- This diagram shows what happens to the membrane potential of the cell when an action potential occurs. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. There is a small key to the right of the page. The diagram is a line graph with the x-axis at the bottom of the page showing time (msec) and the y-axis on the left of the page showing membrane potential (mV). A dotted line extends across the graph at the -70mV point and this depicts the resting potential. An arrow near the beginning of the x-axis shows when the depolarising shock is applied. There is a single solid line on this graph, which starts at the -70 mV point on the y-axis. Just above the -70 mV point is a dashed leader line pointing to the solid line, which is labelled on the left as the threshold of excitation. After this point the solid line rises steeply past the +50mV point. This part of the graph is labelled D with an upwards pointing arrow for depolarisation. After this point the line falls steeply. A downwards pointing arrow R indicates repolarisation. The line dips below the resting potential before rising again to meet it, labelled as the refractory period.
