Glial cells are crucial for the proper functioning of the nervous system. Astrocytes regulate the extracellular environment, provide metabolic support to neurons, and modulate synaptic transmission. Oligodendrocytes are responsible for the formation of myelin sheaths around axons in the central nervous system, which is essential for efficient signal transmission. Microglia act as the immune cells of the brain, constantly surveying the environment and responding to injury or disease.
