RGC regeneration can be induced by cooperation of these substances. The contact of RGC axons to Schwann cells based …
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 … WebSchwann cells (SCs) are the major glial cell type in the peripheral nervous system. They play essential roles in the development, maintenance, function, and regeneration of peripheral nerves. In the mature nervous system, SCs can be categorized into two major classes: myelinating and nonmyelinating cells. Myelinating SCs provide the myelin ...
