Glial cells make up more than 50% of the cells in the nervous system, and if they are destroyed, less than 20% of the cells of the nervous system would remain. Glial cells have numerous functions, including supporting, protecting, and nourishing neurons, and their destruction would have a profound impact on the nervous system. The other answer choices are not accurate because the destruction of glial cells would affect both the CNS and PNS, would not result in a reduction in the mass of the nervous system, and would not directly affect the choroid plexus's ability to generate cerebrospinal fluid.
