Yes, but I was under the impression that the depolarization happened across 
the cell membrane, rather than having ions or free electrons moving *along* 
the nerve like a wire.

In other words, unlike a few messages up, it's not "electrical power" that's 
causing muscles to move and such. There's no electricity coming into or out 
of the nerve, but rather a change of potential across the membrane.

I don't really know much about it, tho.
