Understanding the Brain’s Anatomy – Brain Cells
Brain cells are classified into neurons and glial cells. Glial cells have different kinds, and brain tumor types depend on which glial cell it originated from.
Glial cells that are star-shaped are called astrocytes. These cells reproduce even as the brain matures, and may be prone to abnormal cell replication causing tumors in the central nervous system.
Oligodendrocytes are glial cells that are found around the axons in nerve cells, and serve as myelin sheath or insulation.
Ependymocytes are glial cells that make up the membrane that coats the brain ventricles and spinal cord’s central canal.
Microglial cells act as scavengers that proliferate and devour damaged cells in the central nervous system.
