What is the primary function of glial cells?

The primary function of glial cells is to support and protect neurons. These non-neuronal cells play several crucial roles in the nervous system. They provide structural support, maintain homeostasis, and form myelin, which insulates axons and enhances the speed of electrical impulse conduction. Glial cells are also involved in the repair and maintenance of nervous tissue, helping to manage the environment around neurons and maintaining the health of the nervous system. This support is vital for the proper functioning of neurons, ensuring they can transmit signals effectively and respond to various physiological demands. Their protective role includes the removal of waste products and pathogens, thus contributing to overall neural health and stability.
