Which term best describes non-neuronal cells that maintain homeostasis, form myelin, and provide support for neurons?

Which term best describes non-neuronal cells that maintain homeostasis, form myelin, and provide support for neurons?

• A. Neurons
• B. Glia
• C. Astrocytes
• D. Oligodendrocytes

Answer: (B)

Glial cells are the non-neuronal partners of neurons that keep the environment around neurons stable, help regulate ion and neurotransmitter balance, provide metabolic support, and wrap axons with myelin to speed up signaling. This broad term covers all supporting cell types in the nervous system, including astrocytes and oligodendrocytes. Neurons are the cells that transmit signals, while astrocytes and oligodendrocytes are examples of glial cells. Because glia encompasses these roles—homeostasis, myelination, and general neuronal support—it is the most accurate descriptor for non-neuronal cells that maintain homeostasis, form myelin, and support neurons.
