Recent proteomic studies have identified many additional, minor components of the myelin sheath whose functions are still being elucidated but likely contribute to the organization and integrity of the sheath. Web10) The brain and spinal cord contain fatty material called myelin. In the brain and spinal cord, it is created by specialized glial cells called oligodendrocytes. When the myelin sheath serves as an insulator, nerve impulses can move more quickly and effectively. The outermost layer of the brain, known as the white matter, contains myelin.
