   "Increased ECF calcium also raises the threshold potential, again making it harder to create an action potential, but, when an action potential is reached, a greater number of neurotransmitter vesicles are released." Partly true. ECF can and does rai...

   Volatile, Ca++ does not bind to Potassium channels receptors, in this case of this discussion at least. in the focus of this discussion it is the opening of Ca++ channels that causes activation of the membrane by the ability of Calcium to flow thro...

   "HeartICU", you're mostly correct. Increasing extra or intra cellular concentrations of ions doesn't change action potential thresholds. AP thresholds don't change; at least not due to quantitative changes of ion presence or absence. In the case o...
