Glia or Glial Cells


Other cells in CNS, "glia/ glial cells" comes from "glue,”
One-tenth the size of neurons.
Number of glial cells is ten times greater than neurons in the brain (approximately 1011 neurons and 1012 glial cells),
Constitute approximately half of the overall mass of the brain.
White matter consist predominantly of glial cells and a small volume of axons.
There are three types of glia: They arise from two different embryological lines.
        astrocytes,
        oligodendrocytes, and
        microglia
