This is Glial, a little character I made up about 2 years ago to help me study for a Biology exam. (That’s why it has my old signature on it, didn’t feel like fucking with it.)
The neuroglia or glial cells in the brain serve to provide support and insulation between neurons by surrounding them. They also assist in nervous system repair and maintenance, helping with development of the nervous system and even providing metabolic functions for neurons. I like to think of them as the housekeeper cells for the brain.
