The myelin sheath serves to insulate axons of neurons in the brain and spinal cord along with axons outside the brain and spinal cord. It is composed of Schwann cells outside the central nervous system (CNS). The Schwann cells wrap around an axon many times to prevent messages from short-circuiting between neurons.
