a: Each nerve cell ~
b: a little power plant
What:
"Electric shock can cause a muscle twitch only because it can cause the nerves to fire. We can measure a current off of nerves because they work by a flow of ions through a membrane, but they still arent the same thing as an electrical wire carrying a current. Each nerve cell is like a little power plant and their only function is to tell the next nerve in line to do the same thing that it just did. "
