Web1 jan. 2014 · The resting membrane is also permeable to Na + and Cl − and therefore the resting membrane potential is approximately −75 to −40 Mv – in other words, substantially positive to EK. An action potential is generated by the rapid influx of Na + ions followed by a slightly slower efflux of K + ions. Web(corrected prediction)-Exceeding threshold depolarization at the trigger zone INCREASES the likelihood of generation of an action potential. As indicated in table 1. An action potential is generated when the threshold is met at -55 mv. Action potential amplitude does not change with distance-Correct as indicated in table 1.
