Satellite Cells
Microglia
Astrocytes
Oligodendrocytes
Line central cavities of the brain. Form a permeable barrier between CSF and cells of the CNS.

Ependymal Cells
Satellite Cells
Schwann Cells
Wrap around fibers producing insulating coverings (myelin Sheaths)
Satellite Cells
Oligodendrocytes
Schwann Cells
Astrocytes
Surround neuron cell bodies within ganglia. Protection.
Schwann Cells
Satellite Cells
Microglia
Ependymal Cells
Surround and form myelin sheaths around the larger nerve fibers in the PNS. Vital to regeneration of nerve cells.
