: These line the brain's ventricles and help produce and circulate cerebrospinal fluid (CSF) using hair-like cilia. Peripheral Nervous System (PNS)
: Function similarly to oligodendrocytes by forming myelin sheaths around axons in the PNS, but also aid in nerve regeneration. neuroglia
: The brain’s resident immune cells. They act as macrophages, scavenging for dead cells, debris, and pathogens. : These line the brain's ventricles and help
Neuroglia, often called the "unsung heroes" of the nervous system, are non-neuronal cells that outnumber neurons and provide the essential support framework for the brain and spinal cord. While neurons handle information processing, neuroglia manage everything from immune defense to the physical insulation of nerve fibers. 🧠 Major Types of Neuroglia scavenging for dead cells
