Glial Cells

Glial cells are the supportive cells of the nervous system, often called the brain's "helper cells." They do not transmit nerve impulses like neurons but perform essential roles such as providing structural support, nourishing neurons, insulating nerve fibers to ensure efficient signal transmission, and protecting against damage or infections. Glial cells also help in waste removal and repair parts of the nervous system after injury. They are vital for maintaining a healthy environment for neurons to function properly, contributing significantly to overall brain health and activity.
