Glial cells play a crucial role in supporting and protecting neurons, which is essential for maintaining the overall health and functionality of the nervous system. Unlike neurons, which are primarily involved in transmitting electrical signals and processing information, glial cells fulfill a variety of supportive roles. They provide structural support to neurons, ensuring proper organization and integrity within the nervous system. Additionally, glial cells are involved in the maintenance of the extracellular environment, regulating ion concentrations, and removing excess neurotransmitters, all of which are vital for creating a stable environment for neuronal function.

Glial cells also play important roles in insulate neurons, such as the myelin sheathing provided by oligodendrocytes in the central nervous system, which enhances the speed of electrical transmission along axons. Furthermore, these cells contribute to the repair process following neural injury and can modulate synaptic function and plasticity. Therefore, their supporting and protective functions are fundamental in ensuring efficient communication between neurons and maintaining the health of the nervous system overall.
