Glia -

: Act as the brain’s immune system, scavenging pathogens and dead cells.

: They regulate neurotransmitter levels and support neuronal health. : Act as the brain’s immune system, scavenging

: Glia actively help induce and eliminate synapses. maintain the extracellular environment

: Form the myelin sheath around axons to speed up electrical signals. Oligodendrocytes work in the central nervous system (CNS), while Schwann cells are in the peripheral nervous system (PNS). and provide structural support.

In neuroscience, (or glial cells) are non-neuronal cells that provide support and protection for neurons. While once thought to be simple "glue," they are now known to be essential for brain development and function. Main Types of Glia:

: Provide nutrients to neurons, maintain the extracellular environment, and provide structural support.
