What is suprasternal notch?

The suprasternal notch, also known as the jugular notch or the fossa jugularis sternalis, is a large, visible dip or hollow located at the top of the sternum (breastbone) in the center of the chest. It is found just above the manubrium, the uppermost part of the sternum.

The suprasternal notch is an important anatomical landmark that is used by healthcare professionals to identify the level of the second rib, which is significant for counting ribs and locating other structures in the chest. It also serves as a visible reference point for determining the level of the thoracic vertebra T2.

In addition, the suprasternal notch is an important landmark for CPR (cardiopulmonary resuscitation) training, as it is used as a location to place fingers for performing chest compressions on adults. It is also used as a reference point for measuring neck circumference in medical assessments.

Overall, the suprasternal notch is a prominent and easily identifiable feature of the sternum that serves various anatomical and clinical purposes.
