Schwann cell plasticity. PNS has a very good regenerative capacity, and this is largely due to Schwann cells that develop a high plasticity and can contribute very quickly to the regeneration of peripheral nerves after injury whether it is a trauma or a pathological condition. 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 … shape of water watch online
