WebOften axons are wrapped by myelin sheaths, leaving exposed sections ( node of Ranvier) between segments of myelin. Myelin is produced by oligodendrocytes (glial cells) in the CNS and Schwann cells in the PNS; it acts as electrical insulation, speeding information conduction down the neuron. WebFigure 1.5. Myelin wraps around and insulates the axon. The spaces between the myelin sheath, where the axon is uncovered, are call the Nodes of Ranvier. ‘Myelin’ by Casey Henley is licensed under a Creative Commons Attribution Non-Commercial Share-Alike (CC-BY-NC-SA) 4.0 International License.
