Glial cells are non-neuronal cells that make up the majority of cells in the human nervous system. They play important roles in supporting, protecting, and nourishing neurons. One of their primary functions is to form myelin, a fatty substance that insulates neurons and helps them transmit signals more efficiently. Glial cells also help form the blood-brain barrier, which protects the brain from harmful substances in the blood. They respond to injury by migrating to the site of damage and releasing chemicals that promote healing. Additionally, glial cells are involved in learning and memory processes.
