Brain cell. Transmission electron micrograph (TEM) of a section through an oligodendrocyte in human brain tissue,showing free ribosomes (dark blue dots),golgi apparatus (curved light blue lines),lysosomes (dark blue circles) and mitochondria (green). The cell nucleus (large,dark) is a lower left. Oligodendrocytes occur in both the white and grey matter of the central nervous system (CNS). Their main function is to provide support and to form myelin sheaths around neurons (nerve cells),which insulates the axon of each cell,allowing efficient transmission of electrical impulses.
