Multiple sclerosis is a debilitating autoimmune disease that results in the loss of the insulation around neuron axons. What cell type is the immune system attacking, and how does this disrupt the transfer of messages by the nervous system?

But I've won. This is Ricky and today we're working on Problem 25 from Chapter 35. So multiple sclerosis and the my own nation. So to understand why de Milo Nation is bad, we have to remember where we have to remind ourselves while mild, why Meilan is good. So Milon X eyes, no ronel insulation. And so what? That means it increases actual potential speed, and it also decreases loss of signal. So that means without Milon we see a loss of signal and also a decrease in action potential speed. That's for you. It's helpful seeing the next one.

Russian here. Ask what? The disease, multiple sclerosis is so in this particular disease here, it makes it such that the myelin sheath is destroyed and therefore the nerve conduction speed is going to be slowed down dramatically. This basically makes it such that the correct answer for this question is going to be a here.

In here. Ask what? Multiple sclerosis is a disease off. So we know that multiple sclerosis is basically when we have a deficiency in, um, near ronel transport. So this essentially only happens, whatever. We have something faulty within our neurons and the question that basic will the answer choice rather that basically best answer this is basically going to be a war. Patches of Meiling are going to destroy. So what happens is when we know that Meilin sheets are basically functioning in the transport of action potentials throughout the neurons. And if these are basically destroyed, neuron transport and actually the transport of actual potential is going to be slowed down dramatically, which causes this condition here.

Are your introduced to a disease called multiple sclerosis here. And what happens in someone with multiple sclerosis is that their axe ons become de violin ated. And what that means is there axe ons begin to lose Meiling. And so in ordinance, this question. We need to know what Meilan is. Meilin is a type of glial cell. Oh, or at least it's formed by types of glial cells that insulate your axe ons So that action potentials, which I abbreviate here AP can travel fast enough through them to produce the desired response. And so the type of cells that make up mile and there's two of them. There's Schwann cells, and there are all ago Dender sites in the difference between these types of, um, glial cells that make up Meilin is their location. And so Schwann cells produce smiling in nerve cells in the peripheral nervous system, and then Oleg Odin Dender sides produce Meilin and sales in the central nervous system. And so this question is saying that if someone has multiple sclerosis and their axe ons are specifically de Meilin ated in the central nervous system, what cells do you think are being affected? and so that what we would look at is because there's two different types of cells that cause Milon these two right here, uh, that we would look for the one that produces mile in in the central nervous system. And what we see there would be the old ago dangerous sites. And so that would be the one that you would want to highlight as being targeted by multiple sclerosis. And so make sure to include that in your answer.
