Myelin
Myelin is a fatty tissue that surrounds nerve cells, in particular the nerve cell axon. This tissue is formed by other kinds of cells that support nerve cells called glial cells ( schwann cells in the peripheral nervous system and glial cells in the brain and spinal cord. By insulating the nerves it helps the tiny electric signal that conducts impulses to travel quickly down the nerve cells.
