Glia or Glial cells

The supporting cells of the body’s nervous system.

There are many different types of glial cells and they greatly outnumber neurons. They help to form the blood brain barrier and play a critical role in protecting and nourishing neurons. The major types in the central nervous system are astrocytes, oligodendrocytes, ependymal cells, and microglia. In the peripheral nervous system the main types are Schwann cells and satellite cells.
