oligodendroglia

 [ol″ĭ-go-den-drog´le-ah]
1. the non-neural cells of ectodermal origin forming part of the adventitial structure of the central nervous system.
2. the tissue composed of such cells.

ol·i·go·den·drog·li·a

(ol'i-gō-den-drog'lē-ă), This word is grammatically singular. Avoid the mispronunciation oligodendrogli'a.
One of the four types of glia cells (the other three being macroglia or astrocytes, ependymal cells, and microglia) that, together with nerve cells, compose the tissue of the central nervous system. Oligodendroglia cells are characterized by variable numbers of veillike or sheetlike processes that are each wrapped 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, and accordingly are more numerous in white matter than in gray matter.
Synonym(s): oligodendria

Neuroglia consisting of cells similar to but smaller than astrocytes, found in the central nervous system and associated with the formation of myelin.

It is quite conceivable, for example, that all the steps may be carried out in cells of the urinary tract, or that they may be carried out in oligodendroglia, and that no intermediary cell types may be involved.

As no other function except nourishment has been ascribed these mysterious "neuroglia, especially the astrocytes, oligodendroglia and microglia" as Yahoo has it, we will not be stepping on anyone's toes.
Astrocytes and microglia provide physical and nutritional support for neurons; oligodendroglia and Schwann cells provide insulation to neurons; and satellite cells offer physical support for neurons.
Anterior horn cells showed degeneration and neuronal cell death; conversely, no changes were seen in the oligodendroglia or peripheral nerves.
Understanding that the precursors to oligodendroglia are particularly vulnerable to free-radical attacks leads to the question, can this injury be prevented by using free-radical scavengers?
Glial cells (destined to become oligodendroglia and lay down myelin) are either destroyed (causing necrosis) or transformed (resulting in hypertrophic astrocytes and damaged glia).
The cell that makes myelin in the CNS is the oligodendroglia (or "oligo") cell.[1] In addition to myelin, MS also affects oligos.
