Neuroglial cells, or glia, support and protect neurons. They do not transmit signals but play crucial roles in maintaining the homeostasis, forming myelin, and providing support and protection for neurons. Types of neuroglial cells include:
Astrocytes: Maintain the blood-brain barrier and provide nutrients to neurons. Oligodendrocytes: Form the myelin sheath in the CNS. Schwann Cells: Form the myelin sheath in the peripheral nervous system (PNS). Microglia: Act as the immune cells of the CNS. Ependymal Cells: Line the ventricles of the brain and the central canal of the spinal cord.
