what is the difference between white and gray matter
The difference between white matter and gray matter is that white matter contains myelinated axons and the gray does not. This myelination is fat insulation surrounding the axâ¦ons that insulates and makes nerve impulses happen faster.
1. Grey matter is made up of nerve cell bodies, and white matter is made up of fibers. 2. Unlike the white matter, the neurons of grey matter do not have extended axons. 3. Grey matter occupies 40 percent of the brain, while white matter fills 60 percent of the brain.
