MEDICAL PHYSIOLOGY

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: -In the central nervous system, glia develop from the ventricular zone of the neural tube. These glia include the oligodendrocytes, ependymal cells, and astrocytes. In the peripheral nervous system, glia derive from the neural crest.
