Hope this helps.

ms is an autoimmune disorder wherein the body's immune system "attacks" a substance called myelin, which insulates nerve cells. nerve cells, just like a copper wire, conduct electricity. and, like the conducting wire between your computer and your wall, the nerve cells are wrapped in a sheath. in the nervous system, the sheath is made of myelin. in ms, the body's immune system "chews up" the myelin.
