Card 9 / 25:
Multiple sclerosis causes demyelination of axons in the brain and spinal cord. Why is this problematic?
Myelin provides insulation for signals traveling along axons. Without myelin, signal transmission can slow down and degrade over time. This would slow down neuronal communication across the nervous system and affect all downstream functions.
