Ependymal Cells— line the ventricles within the brain and make cerebrospinal
fluid
2. Astroglia— star-shaped; provide both nutrients and structural support to

3. Microglia— tiny glia; fight infections and remove debris
4. Oligodendroglia— glia w/ few branches; insulate neurons in the central nervous
system
