i'm getting confused now as i feel like i am just repeating myself!
there is a graph showing change in potential difference across membrane against time. One graph is moderate pressure and the other is light pressure. there are two points A and B. A = light pressure small action potential and B = medium pressure large action potential. The questions are asking about the differences etc but one asks heavier pressure was applied so point A increased, what would happen to point B?
and then it goes on to say in a further experiment the outer layers of the Pacinian corpuscles were removed, exposing the end of the nerve fibres. It then shows a graph with point A and B, A at around 20mV and B at around 90mV...? any help?
