<prompt> Features of Neuroglia cells include all except:Protoplasmic astrocytes are found in grey matterOligodendrocytes are derived from ectodermMicroglia are mesodermal in originCentral neuroglial cells are derived from Schwann Cells  <response>: D i.e. Central neuroglial cells are derived from schwann cells Schwann cells form myelin around axons in the peripheral nervous systemQ. They are not found in central nervous system. In CNS myelination is done by oligodendrocyteQ.
