Is the process by which nerve cells are coated with insulation that enhances the speed and efficiency?

Answer;

-Myelination

Explanation;

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.

-Myelination process takes place when a substance called myelin, which is made up of fatty lipids and proteins, accumulates around nerve cells, or neurons. Myelin plays an essential role in the health and function of nerve cells, the brain, and the nervous system.
