Etymology

Tonus comes from the Greek tonos, which means 'stretch' or 'tension', and is the same root as the English words tone and tonic. Think of a tight guitar string: that small, steady pull helps the string respond when you touch it, and tonus is the body's steady, slight tension that lets muscles and vessels respond to signals.
