9696460975	threshold	the level of depolarisation required to cause an increase in Na+ permeability (pNa). Beyond this point the action potential is an 'all-or-none' event.	0
9696465767	overshoot	the inside of the neurone becomes +ve to the outside, as the system is driven towards ENa	1
9696469142	resting potential	is dictated mainly by K+	2
9696472751	falling phase	he switch from high pNa to high pK allows the driving forces causing K+ exit (+ve potential inside and concentration gradient) to come into play	3
9696475654	undershoot	the system is driven towards Ek, before returning to its resting state	4
9696520653	Rising phase	the rapid depolarisation occurs as the large driving forces causing Na+ entry (-ve potential inside and concentration gradient) come into play	5
