oligodendroglia

oligodendroglia (ol´I-go-den-drog´le-a)

One of the three types of glia cells (the other two being macroglia or astrocytes, and microglia) that, together with nerve cells, compose the tissue of the central nervous system. O. cells are characterized by variable numbers of veillike or sheetlike processes that are wrapped each around individual axons to form the myelin sheath of nerve fibers in the central nervous system (compared with Schwann cells in the peripheral nervous system); forms myelin in the central nervous system; accordingly, they are more numerous in white matter than in gray matter.oligodendria; [oligo- + G. dendron, tree, + glia, glue]
