Glial cells provide what type of support to neurons?

Glial cells provide what type of support to neurons?

• A. Store memories
• B. Provide electrical signals
• C. Support neurons
• D. Transmit impulses

Answer: (C)

Glial cells provide the essential support neurons need to function. They act as the scaffolding that holds neurons in place and surround their processes, create and maintain the myelin insulation that speeds up signal transmission along axons, and help keep the neuronal environment stable by delivering nutrients, clearing waste, and regulating ions and neurotransmitter levels. They also play roles in immune defense and in shaping synapses during development and plasticity. Because of these supporting functions, glial cells are described as providing support to neurons. Memories are stored through changes in neural connections, not by glia, and the actual electrical signals and transmission of impulses are carried by neurons, not glial cells.
