How the Body Works : A Nerve Impulse

Wow heaps good :D

thanks :D

This video was helpfull :)

Thank you for adding this! Most helpful video I've found

wooow im naked right now! w

that's still the inside of the cell...outside the cell Na+ exists.

Just a skipped detail for everybody: At the end of the REpolarization (in which the cell becomes negative again)the Na+ K+ pump restablishes the Na+ outside the membrane and the K+ inside the cell.

its showing in what direction the ions are moving, not the highest concentration

That voice really sounds like HAL...

yes you r right!

when its polarised, the inside of the cell is negative relative to the outside of the cell an dat this point there's a high conc. of K ions inside and a low conc.of k ions outside, k tends to move into the membrane against its electrochemical gradient--which maintains the resting potential
