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

: The brain’s resident immune cells. They act as macrophages, scavenging for dead cells, debris, and pathogens.

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
