Web9. aug 2024 · These gaps between the myelin sheath are called the Nodes of Ranvier. Both Schwann cells and Oligodendrocytes produce nodes, but there are far fewer of them present in the neurons of the... WebAs the Schwann cell continues to wrap around the axon, all the spaces between its plasma membranes, both cytosolic and exoplasmic, are reduced. Eventually all cytosol is forced out and a structure of compact stacked plasma membranes is formed. Composition: -80 % lipid, 20% protein, (mostly made up of cell membrane)
