And so the third layer is like right here, and you can see this layer is peeled away, the arachnoid, and under here I'm now touching pia, and pia is the external layer of the brain cells themselves, the brain tissue.

So this is a beautiful brain, and it would be positioned in my head like this.

So front of the brain, back of the brain, coming down, hanging down as the spinal cord.

And then as you look at the spinal cord, this is called the cauda equina or cauda equina.

And these are the nerves that are actually going to go down into your lower extremity.

Push it, push it, push it, push it, push it, push it, push it.

Well, you can do that with a computer.

You plug it in and it stays on until you turn it off or it blows up.

We have to go to sleep.
