Published	10/26/2023	{{c1::Schwan Cells}} are a structure unique to the Peripheral Nervous System (PNS) that speed up the impulse via myelenation.
Published	10/26/2023	{{c1::Oligodendrocytes}} are unique to the Central Nervous System (CNS), and plays a role in myelin formation
Published	10/26/2023	{{c1::Astrocytes}} help form barriers like the blood-brain barrier and are unique to the CNS
