 |
| Oligodendrocytes Oligodendrocytes produce the myelin sheath around nerve fibers of the CNS. |
Astrocytes
Astrocytes form a scaffolding through the grey matter of the CNS attaching neurons and capillaries of the brain. |
 |
 |
| Microglia Cells Microglia cells (dark staining cells) phagocytizes microorganisms and dead cells in the CNS |
Ependymal Cells Ependymal Cells form sheets of cells that line canals and spaces of the CNS. Take part in creating fluid and moving fluid. |
