WebJul 8, 2024 · Figure 2: Different types of glial cells 6. Schwann Cells: Schwann cells are named after Theodor Schwann, a physiologist who explored them. They act similarly to oligodendrocytes in the sense that they supply myelin sheaths for axons, but they are found in the peripheral nervous system (PNS) instead of the central nervous system (CNS). WebOligodendrocytes are a type of glial cell that helps create the myelin sheath, the fatty coating around nerve cells keeping them insulated and protected. Schwann cells, located in the peripheral nervous system, also support axonal myelin formation. Myelinated axons exist primarily in the brain’s white matter.
WebOligodendrocytes (from Greek 'cells with a few branches'), or oligodendroglia, are a type of neuroglia whose main functions are to provide support and insulation to axons in the central nervous system of jawed vertebrates, equivalent to the function performed by Schwann cells in the peripheral nervous system.Oligodendrocytes do this by creating the … WebBy imposing saltatory conduction on the nervous impulse, the principal role of the myelin sheath is to allow the faster propagation of action potentials along the axons which it surrounds.
