Internodes of an axon
WebOligodendrocyte (OL) myelination is a critical process for the neuronal axon function in the central nervous system. After demyelination occurs because of pathophysiology, remyelination makes repairs similar to myelination. Proliferation and differentiation are the two main stages in OL myelination, and most factors commonly play converse roles in … WebRather, each myelin sheath insulates the axon over a single section and in general, each axon comprises multiple long myelinated sections separated from each other by short gaps called the nodes of Ranvier. Nodes of Ranvier are the short (~1 micron) unmyelinated regions of the axon between adjacent long (~0.2 mm – >1 mm) myelinated internodes 1).
