Detailed explanation-1: -Oligodendrocytes are the myelinating cells of the central nervous system (CNS).
Detailed explanation-2: -OPC are distributed throughout the CNS and represent a pool of migratory and proliferative adult progenitor cells that can differentiate into oligodendrocytes. The central function of oligodendrocytes is to generate myelin, which is an extended membrane from the cell that wraps tightly around axons.
Detailed explanation-3: -Three of these, astrocytes, oligodendrocytes, and microglia, are found only in the central nervous system (CNS). The fourth, the Schwann cells, are found only in the peripheral nervous system (PNS).
Detailed explanation-4: -Oligodendrocytes and OPCs in the Normal CNS ‘ Like other glia, oligodendrocytes are found throughout the CNS gray and white matter, where individual oligodendrocytes can myelinate as many as 40–50 axons. This important function enables rapid saltatory conduction throughout the CNS.
