How does myelination impact the rate of nervous impulse conduction, include examples

Myelination increases the speed of nervous impulse conduction. Allows saltatory conduction - the impulse can jump from node (of ranvier) to node, rather than travelling continuously which takes longer. Example - in MS the integrity of the myelin sheath decreases due to an autoimmune response, resulting in failure of the nervous system to coordinate movement.
