The cells that make up myelin and astrocytes are collectively considered glial cells. They are supporting cells that help keep neurons working properly. Think: TV show producer supporting the star or the defensive line coach supporting the defensive line.
Some recent research has shown that they may even be able to send signals and be part of the way the brain sends information.
They are super important. To drive that home…Can you find any diseases or disorders that are linked to malfunction or loss of glial cells? In other words, what happens if they aren’t there and working properly?
