WebMyelin sheath definition, a wrapping of myelin around certain nerve axons, serving as an electrical insulator that speeds nerve impulses to muscles and other effectors. See more. WebThe process of myelination begins by a Schwann cell first engulfing several axon segments at once (Figure 1(a)).These are sorted out until the cell selects only one axon segment to wrap with myelin (Figure 1(b)).Formation of extracellular matrix is an essential early step in the process, and in cell culture, myelination will not commence until ascorbic acid is …
