Neuroglia, also called glial cells or simply glia, is non-neuronal cell in the central nervous system (brain and spinal cord) and the peripheral nervous system. They have a supporting role in the protection and maintenance of neurons.

Explanation: There are two groups of cells that comprise the human nervous system – neurons and neuroglia. This means neuroglias are cells in our nervous system that are not neurons. They just maintain the environment inside the nervous system to in equilibrium. They regulate homeostasis.
