WebThe best thing to do would be to surround this entire axon with a good insulator. And for the most part, that is true. It is surrounded by a good insulator. That is what the myelin sheath is. So let's say we want to surround this whole thing with just one big grouping of Schwann's cells, so one big myelin sheath-- which is a good insulator. WebANS A. Myelin is formed by Schwann cells in the peripheral nervous system ( PNS) oligodendrocytes in the central nervous system (CNS). Each Schwann cell forms a single …
