In project management, a change order is a component of the change management process whereby changes in the Scope of Work agreed to by the Owner, Contractor and Architect/Engineer are implemented.
Oligodendrocytes is located in the central nervous system. It is a type of neuroglia (group of cells that support neurons). Its function is to produce myelin sheaths around CNS nerve fibers. Oligodendrocytes are types of cells that make up the supportive or glial tissue of the brain.ligodendrocytes are found in the central nervous system, primarily in the brain but also in smaller numbers in the spinal cord. Oligodendrocytes are small, rounded cells with one or a few processes, or extensions.
Oligodendrocytes do this by creating the myelin sheath, which is 80% lipid and 20% protein. A single oligodendrocyte can extend its processes to 50 axons, wrapping approximately 1 Î¼m of myelin sheath around each axon; Schwann cells, on the other hand, can wrap around only one axon.ligodendroglia, types of glial cells, arise during development from oligodendrocyte precursor cells, which can be identified by their expression of a number of antigens, including the ganglioside GD3, the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF-alphaR).
