Cells: The word "glial" comes from a Greek word meaning "glue." These supporting cells form a protective coating and nourishment for neurons. They are also essential in providing structural support ("scaffolding") for growing and developing neurons. Glial cells multiply throughout the human lifespan.
Pertaining to the supporting cells of neural tissue.
scars are produced by enlargement of the fibrils of astrocytes (a type of glia) that normally support the nerve cells and their nerve fibers. When a portion of the nervous system is damaged, these fibers enlarge and replace the damaged area. This process is referred to as Gliosis.
