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.
Myelin sheath. made up by oligodendrocytes in the central nervous system and schwann cells in the peripheral nervous system; provides protection and insulation for the axon, and also increases teh speed of conductivity of the nervous impulse; myelinated axons are also calle dmyelinated fibers.yelin sheath. made up by oligodendrocytes in the central nervous system and schwann cells in the peripheral nervous system; provides protection and insulation for the axon, and also increases teh speed of conductivity of the nervous impulse; myelinated axons are also calle dmyelinated fibers.
