Myelin is a substance which encloses the axons of neurons, providing electrical insulation that helps the nervous system function. The importance of this substance is most evident in the types of diseases that develop when it is damaged or destroyed.
The white lipid material that insulates the axon of a neuron is called myelin. In the central nervous system, myelin is created by oligodendrocytes while in the peripheral ner â¦ vous system the myelin is created by Schwann cells.The purpose of myelin is to speed up action potentials.n the central nervous system, myelin is created by oligodendrocytes while in the peripheral ner â¦ vous system the myelin is created by Schwann cells.
