What is the primary role of glial cells in the nervous system?

The primary role of glial cells in the nervous system is to provide structural support and maintenance for neurons. Glial cells, also known as neuroglia, are non-neuronal cells that play a crucial supportive role. They help maintain homeostasis, form myelin, and provide support and protection for neurons. Additionally, they can participate in synaptic transmission and modulate neuronal activity, but their main function revolves around maintaining the overall health and environment of the neuronal networks.

These cells contribute to the functionality of the nervous system by creating a supportive framework that sustains neuronal cells, ensuring they are nourished and able to function properly. Their role is essential for the overall integrity and efficiency of neural processes, distinguishing them from neurons that are primarily involved in the transmission of electrical signals.
