Neuroglia Apr 2026

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

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 neuroglia

: The most abundant glial cells. They maintain the blood-brain barrier, regulate the chemical environment (like potassium ions), and provide nutrients like lactate to neurons. : Surround neuron cell bodies in ganglia to

: These cells produce myelin , a fatty sheath that wraps around axons to speed up electrical signals. 🧠 Major Types of Neuroglia : The most

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

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