In the central nervous system, glial cells include oligodendrocytes, astrocytes, ependymal cells and microglia, and in the peripheral nervous system glial cells include Schwann cells and satellite cells . The term derives from Greek γλία and γλοία "glue"; pronounced in English as either / ˈɡliːə / or / ˈɡlaɪə / </P> <P> As the Greek name implies, glia are commonly known as the glue of the nervous system; however, this is not fully accurate .
