"glial cell" 的定义和意义

What is a "glial cell"?

A glial cell, also known as neuroglia, is a non-neuronal cell in the central nervous system that provides support and protection to neurons. Glial cells play crucial roles in maintaining the structure and functionality of the nervous system, assisting in neuronal development, and regulating the extracellular environment. They contribute to the overall health and function of the brain and spinal cord, helping to insulate and nourish neurons, remove waste products, and support immune responses.
