Myelin

adam.about.net
Definition: Each nerve cell in the body is coated with a layer of fats and protein called myelin. The myelin protects the nerve cell and helps it to conduct electrical signals faster. In MS, the immune system mistakenly attacks the myelin around nerve cells, causing demyelination. These nerves with damaged myelin do not function as efficiently, causing the symptoms of MS.
