PATHOLOGY

Detailed explanation-1: -Astrocytes, which are restricted to the brain and spinal cord, have elaborate local processes that give these cells a starlike appearance (hence the prefix “astro”). The major function of astrocytes is to maintain, in a variety of ways, an appropriate chemical environment for neuronal signaling.

Detailed explanation-2: -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.
