Myelin in the CNS consists of multiple layers of plasma membranes that are assembled by oligodendrocytes. Myelin in the PNS are similar in architecture but they’re produced by Schwann cells and not oligodendrocytes, and the proteins and lipids that the sheath is made of are different. Therefore, most diseases of CNS myel..."
