Glial Cell

Example(s):
- Astrocytes: These cells provide structural support for neurons and help to regulate the extracellular environment. They also play a role in signaling between neurons and in immune responses in the brain.
- Oligodendrocytes: These cells produce myelin, a fatty substance that insulates axons and helps to speed up the transmission of nerve impulses.
- Microglia: These cells are the immune cells of the brain. They scavenge for debris and infections, and they also play a role in neural development and repair.
- Ependymal cells: These cells line the ventricles of the brain and help to produce cerebrospinal fluid.

Counter-Example(s):
- a Neuron Cell.

- Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses. The neuroglia make up more than one half the volume of neural tissue in our body. They maintain homeostasis, form myelin in the peripheral nervous system, and provide support and protection for neurons. In the central nervous system, glial cells include oligodendrocytes, astrocytes, ependymal cells and microglia, and in the peripheral nervous system they include Schwann cells and satellite cells.
