Neuroglia

: These cells produce myelin , a fatty sheath that wraps around axons to speed up electrical signals.

: Surround neuron cell bodies in ganglia to provide physical support and regulate their chemical environment. neuroglia

: Function similarly to oligodendrocytes by forming myelin sheaths around axons in the PNS, but also aid in nerve regeneration. : These cells produce myelin , a fatty

: These line the brain's ventricles and help produce and circulate cerebrospinal fluid (CSF) using hair-like cilia. Peripheral Nervous System (PNS) : These cells produce myelin

Neuroglia are categorized by their location in either the Central Nervous System (CNS) or the Peripheral Nervous System (PNS). Central Nervous System (CNS)
