Glial cells

4 important questions on Glial cells

Which glial cells are in the PNS?

1. Satellites cells
2. Swann cells

What is the difference in main function of oligodendrocytes and Swann cells?

These cells myelinate and insulates the axons and allows for faster action potential propagation along the axons. But the oligodendrocytes do this in the CNS and the Swann cells do this in the PNS

What is the function of satellites cells?

They electrically insulate the PNS cell bodies and regulates nutrient and waste exchange for cell bodies in ganglia.
