WebOL myelination is critical to the vertebrate central nervous system (CNS) function. It supports not only the myelinating cell in the CNS but also provides metabolic and trophic support to the myelinated axon. The myelin sheath is essential insulation surrounding axons for conduction in the nervous system. WebOligodendrocytes and Schwann cells. The major function of oligodendrocytes and Schwann cells is the formation of myelin. Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction, of up to 200 m/second. The association of glial cells with axons is also found in invertebrates.

Web13 feb. 2024 · However, whilst Schwann cells myelinate axons of the PNS, the oligodendrocytes provide myelination to axons in the central nervous system (CNS). Also, each Schwann cell forms a single myelin sheath around an axon, whereas oligodendrocytes form myelin sheaths for multiple surrounding axons.
