Web23 feb. 2024 · Functions. Myelin sheath’s primary function is to provide insulation to the axons of the neuron it surrounds. This insulation protects these axons in the same way that electrical wires have insulation. Myelin sheath is a low electrical condenser with high electrical resistance, which means it can act as an insulator without disrupting the ... WebPenfield (1924) reinforced the view that the formation of myelin is likely the main role of oligodendrocytes. However, myelination was not considered their only function. Within the gray matter, a fraction of oligodendrocytes were termed “perineuronal” satellite cells, which did not form myelin, but were in close contact with the cell body of neurons, suggesting …

O Myelin is produced by Schwann cells in the central nervous system and by oligodendrocyte in the peripheral nervous system. Nodes of Ranvier are gaps in the myelin sheath that allow the signal to "jump" down the axon. O Myelin increases the speed of signal transmission along the axon
