glia

Glia are specialized cells in the brain and nervous system that support and protect nerve cells (neurons). They do not send nerve signals themselves but perform essential functions such as providing nutrients, removing waste, insulating neurons with myelin, and helping repair damage. Glia also help maintain a healthy environment for neurons to communicate effectively. They are crucial for brain function and overall nervous system health, making up a significant portion of the cells in the brain. In essence, glia act as the support staff that keep the neural network functioning smoothly.
