    This is absolutely the BEST explanation! Until now I honestly thought I was too dumb to grasp the concept of this, but now I realize no one has EVER been able to explained it in a way (to someone who has zero knowledge) that one can get their head around it and truly understand. Not just try remember a whole lot of info and hope it sticks, but completely understand! Which will only aid in further study, of the ECG for example. This then makes the next subject easier to understand and get your head around and so on and so on. Thank you so much!!!! you guys do an amazing job!!!!

    Great explanation! On another note, the calcium channel yields more calcium inside by triggering the calcium-induced-calcium-release through the sarcoplasmic reticulum. This maintains the plateau at phase 2 of the the action potential.
