Glial cells (including astrocytes, oligodendrocytes, microglia, and ependymal cells) are essential for the proper functioning and support of neurons in the central nervous system. If all glial cells were destroyed, only about 10 percent of cells within the CNS would remain, leaving neurons without their essential support system. The peripheral nervous system, which is outside of the CNS, would not be directly affected by the destruction of CNS glial cells. The rate of neuronal cell regeneration would not necessarily decline significantly, as this is primarily influenced by factors such as age and the specific region of the nervous system affected. The choroid plexus, which produces cerebrospinal fluid (CSF), is not primarily composed of glial cells and would continue to function normally in the absence of CNS glial cells.
