: These line the brain's ventricles and help produce and circulate cerebrospinal fluid (CSF) using hair-like cilia. Peripheral Nervous System (PNS)
: The brain’s resident immune cells. They act as macrophages, scavenging for dead cells, debris, and pathogens.
: Function similarly to oligodendrocytes by forming myelin sheaths around axons in the PNS, but also aid in nerve regeneration.
