<P> Schwann cells supply the myelin for the peripheral nervous system , whereas oligodendrocytes , specifically of the interfascicular type , myelinate the axons of the central nervous system . Myelin is considered a defining characteristic of the ( gnathostome ) vertebrates , but myelin - like sheaths have also been seen in some invertebrates , although they are quite different from vertebrate myelin at molecular level . Myelin was discovered in 1854 by Rudolf Virchow . </P>
