What is the primary role of neuroglia?

• A. Transmit impulses
• B. Insulate neurons
• C. Support and protect neurons
• D. Generate nerve impulses

Answer: (C)

The primary role of neuroglia, or glial cells, is to support and protect neurons. These cells are essential components of the nervous system, providing a variety of functions that enhance the overall health and efficiency of neurons. Neuroglia do not transmit electrical impulses like neurons; instead, they maintain homeostasis, form myelin, and provide support and nourishment to the neurons.

Neuroglia also play a crucial role in the development and maintenance of the nervous system, facilitating communication between neurons. By creating an optimal environment for neuronal function, neuroglia ensure that neurons can effectively transmit signals. Thus, their supportive role is vital for the overall functioning of the nervous system.
