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.
Astrocytes. Astrocytes belong to the 3 types of glial cells in the CNS (the others are microglia and oligodendrocytes). Astroglia is used as a synonym. These cell exhibt usually a star-shaped mmorphology, with many processes extending from the soma.ligodendrocytes. Oligodendrocytes are a variety of neuroglia cells within the central nervous system. In comparison to astrocytes oligodendrocytes are more gracile and form less cell ramifications. Their image in a microscopic cross section is reminiscent of trees with only a few branches-hence the name.
