Which of the following is NOT a function of glial cells?

The function that is not associated with glial cells is the transmission of signals between neurons. Glial cells primarily serve supportive roles in the central nervous system, which include providing structural support to neurons, nourishing them, and protecting them from injury and infection.

Transmitting signals is mainly the role of neurons themselves. Neurons communicate through electrical impulses and neurotransmitters, allowing for the transmission of signals across the nervous system. While glial cells play a crucial role in maintaining the health and environment of neurons, they do not engage in direct signal transmission. This distinction is vital in understanding the overall function of neural networks and the specific roles different cell types play within the nervous system.
