extranigral (English)

Where does "extranigral" come from?

The word "extranigral" combines the prefix "extra-" and the adjective "nigral." "Extra-" comes from the idea of going beyond or outside of something, while "nigral" relates to the substantia nigra, a part of the brain. Thus, "extranigral" literally means "outside the substantia nigra." The term reflects a straightforward blend of Latin-derived components to describe something located beyond this specific brain region.
