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
