Glia -

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:

: 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). In neuroscience, (or glial cells) are non-neuronal cells

: They regulate neurotransmitter levels and support neuronal health. In neuroscience, (or glial cells) are non-neuronal cells

: Act as the brain’s immune system, scavenging pathogens and dead cells. In neuroscience, (or glial cells) are non-neuronal cells

: Line the brain's ventricles and produce cerebrospinal fluid (CSF) . Key Functions:

: Glia actively help induce and eliminate synapses.
