Answer;
It is slowed down dramatically
Explanation;
-The myelin sheath can be described as an insulating layer that is composed of wrappings of the plasma membrane of glial cells that encloses the axons outside the brain and spinal cord. It is a fatty material that coats, protects, and insulates nerves, enabling them to quickly conduct impulses between the brain and different parts of the body.
-In multiple sclerosis the T cells either partially or completely strip the myelin off the fibers, leaving the nerves unprotected and uninsulated. These nerves are not as able to pass messages from the brain to the other body parts. The messages the nerves try to send are delayed or distorted and the messages the brain receives may be misinterpreted.
