The word “neuroglia” comes from two Greek words that together mean
“nerve glue.” Neuroglial cells don’t actually glue anything to anything. When they were first discovered, scientists thought they served a binding purpose, thus their name.
'In much the same way as the movie stars on the screen are only a small fraction of the people involved in making a movie, the behind-the-scenes supporting members for the nervous system are the neuroglial cells.'
