WebFeb 4, 2024 · Schwann cells and axon regeneration. Schwann cells play a vital role in axon regeneration. Any injury to the axon can lead to cell death and axonal degeneration. The vertebrate nervous system relies on the myelin sheath for insulation and as a method of decreasing membrane capacitance in the axon. The action potential jumps from node to node, in a process called saltatory conduction, which can increase conduction velocity up to 10 times, without an increase in axonal diameter. In this sense, Schwann cells are the PNS's analogues of the central nervous system's oligodendrocytes. However, unlike oligodendrocytes, each myelinating …
