What are glial cells primarily known for?

Glial cells are primarily known for their role in supporting and nourishing neurons. They play a crucial part in maintaining the health and functionality of the nervous system. Unlike neurons, which are responsible for transmitting information through electrical impulses, glial cells provide structural support, regulate the extracellular environment, and assist in metabolic processes for neurons. They also facilitate the repair and maintenance of nervous tissue, helping to protect neurons from damage and ensuring they can operate effectively. This supportive function is vital for overall brain health and is a key distinction that characterizes glial cells within the nervous system.
