The cells behind the signal

Before it became today’s word, oligodendroglia was a name for something seen through a microscope. Spanish neuroscientist Pío del Río Hortega introduced the term in 1921; English borrowed it soon afterward.

The name belongs to supporting cells in the brain and spinal cord. They wrap nerve fibers in myelin, an insulating material that helps electrical signals travel faster. A formidable word for cells that help messages arrive.
