Embryological Significance of Glial cells in the Central Nervous System.

Glial cells are essential for the proper functioning of the nervous system, categorized into two groups: macroglial and microglia. Traditionally viewed as passive entities involved in nutrition, support, and insulation, recent insights reveal their crucial role in brain function and plasticity. They serve as key regulators of synaptic activity, influencing information transmission between neurons and impacting processes like learning.
