Location of myelin sheath
WitrynaA myelin sheath is absent from the axon hillock and the terminal ramifications of the axon where synapses are established. In the central nervous system, oligodendrocytes produce myelin sheaths for more than one axon, and the oligocyte cell body remains outside of the myelin sheaths. By contrast, in the peripheral nervous system the … Witryna24 paź 2024 · The morphologic hallmark of remyelination in both human and experimental disease is proposed to be the presence of axons with thin myelin sheaths that have a significant increase in the g ratio (axon diameter/total fiber diameter) (6, 18).Remyelinated axons also have shortened internodal lengths.
