Multiple sclerosis is a neurodegenerative disease in which the body’s immune system attacks and breaks down the white matter in the nervous system.
A. What is another word (other than “white matter”) for the structure or type of cells that are affected in patients with MS?
B. Given what these cells/structures do, what effect on neural transmission do you think MS has?
