Membrane potential is polarize when you those channels open up in a while so tend to flow in we say it die polarizes because if the positive charges flowing in then the charges on the two sides of the membrane the same so we go from polarized deep a lot thenand then I will review this when we starting on Monday because I want you to read this action before I you do Blackline Elite it again afterwhat happens when the sodium flows and it's channels that are next to it detect outflow of anon and the channels all along the membrane open there's a chemical signal to opened the first ones once the unharmed flowing in it opens all of the other channels along that is on so if you go up to the pictured here on the top the signal that chemical signaled that gets the sodium channels open here classes starting to flow in data opens the channel here which opens a channel here which of the channel here all along with the attacks on and that is a nerve impulse very similar to electrons flowing down wire in the electricity model okay.We flip the switch electron start moving there's an electron potential in our wires in our house we flip a switch it allows the electrons to move and that’s electricity in dot human body we have movement of on line’s ok bills seven comic structure the analogy is than electronic charged particle and I’d honestly.
