Final answer:
Glia, also known as glial cells or neuroglia, are supporting cells for neurons that play various important functions in the nervous system.
Step-by-step explanation:
Glia, also known as glial cells or neuroglia, are a type of cell found in the nervous tissue. They serve as supporting cells for neurons, playing various important functions such as guiding developing neurons, buffering ions and chemicals, and providing myelin sheaths around axons. There are several types of glia, including astrocytes, microglia, oligodendrocytes, satellite glia, radial glia, and ependymal cells.
