What do glial cells primarily provide for neurons?

• A. Electrical impulses
• B. Structural support and nutrients
• C. Hormonal secretion
• D. Chemical signaling

Answer: (B)

Glial cells primarily provide structural support and nutrients for neurons, making them essential components of the nervous system. These cells outnumber neurons and have various functions that help maintain a healthy environment for neuronal activity. They provide physical scaffolding for the neurons, ensuring that they are positioned correctly within the nervous system and protecting them from damage. Additionally, glial cells supply the necessary nutrients and maintain the ionic balance required for neuronal function, facilitating optimal activity and communication between neurons. Their role extends beyond basic support, as they are involved in modulation of neurotransmitter levels, removal of waste products, and overall maintenance of homeostasis in the brain. This multifunctional support system is crucial for the efficient functioning of neurons and the overall operation of neural circuits.
