Anatomical terminology

The intertragic notch is a feature of mammalian ear anatomy. In humans, it is the space that separates the tragus from the antitragus in the outer ear.

It is the point specified (although not by that name) in the U.S. Army’s regulation governing the length of sideburns in male soldiers.[1]
