In the peripheral nervous system, the product of the multiple encasement of nerve fibers by the myelin-rich cell membrane evagination of Schwann cells; in the CNS, formed by the supporting oligodendrocytes (glial cells). It is discontinuous (segmented), whereby the segments (internodes) are separated by constrictions (Ranvier-Schnürringe). The fibres wrapped in this way are referred to as marrowy or marrowy.
