any good way of remembering membrane potential? I'm having a hell of a hard time getting them to stick.

You don't need to memorize it, but you do need to know what membrane potentials are. At most all you might need memorize is that there is more potassium intracellular and more sodium extracellular.

I guess thats BR for ya

This is kind of stupid, but it may help if you're having trouble remembering -- if you write Na on a piece of paper, you can think of the hole in the a of Na (for sodium) as a cell. You can write a tiny K (for potassium) inside of the hole in the a. The N is outside of the hole because the concentration of sodium is greater outside, the K is inside the hole because the concentration of potassium is greater inside.

I find very few things stupid, and this is not one of them! Problem solved, thank you!
