If myelin is damaged, these impulses slow down., the protective sheath that surrounds nerves in the central nervous system (CNS)Nerve tissue that resides in and composes the brain, spinal cord, and optic nerve leading to neurological symptoms originating from the brain, spinal cord, and/or optic nerveThe cranial nerves that relay messages from your eyes to your brain to create visual images.
