Explanation;
-Myelination is the process in which neural fibers are coated with an insulating fatty sheath (called myelin) that improves the efficiency of message transfer.
-Most nerve fibers are surrounded by an insulating, fatty sheath called myelin, which acts to speed up impulses. The myelin sheath contains periodic breaks called nodes of Ranvier. By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire length of the nerve fiber.
