Surprised You Didn’t Know About the Suprasternal Notch? Here’s What It Does! You might not recognize the term, but the suprasternal notch plays a quietly vital role in your anatomy. Nestled just above your sternum—or breastbone—this small, ridges-like depression often flies under the radar, yet it serves important functions in the skeleton, muscles, and even breathing. If you’ve never heard of it before, it’s time to expand your body knowledge with an eye-opening look at: What the suprasternal notch does and why it matters. ### What Is the Suprasternal Notch? The suprasternal notch is a small, V-shaped groove located at the base of the sternum, literally “above the sternum” translates to suprasternal. While relatively tiny, this anatomical feature marks the junction between the upper chest wall and the thoracic skeleton. It’s bordered by two prominent ridges—sometimes called the suprasternal ridges—and forms part of the anterior thoracic wall.
