Why must glial cells support neurons? Neurons are specialized cells that receive and send signals to other cells through fragile and thin cellular extensions called axons. Glial cells, which can be divided into several types, have various important functions, such as providing structural support, growth support, and insulation around the axon. In this support of neurons, glial cells have become highly specialized. The glial cells support neurons structurally and maintain their long-term neuronal integrity, and neurons regulate glial cell behavior. These cells communicate with each other to perform important tasks in the nervous system. The nervous system is comprised of two primary cell types: neurons and glial cells.
