Suprasternal Notch

The Suprasternal Notch, also known as the Fossa Jugularis Sterni, is a large, visible dip in between the neck and the collarbone of the human body. It is an important anatomical landmark that provides a central point of reference for measuring the body's symmetry and for medical procedures.

Etymology

The term "Suprasternal Notch" is derived from the Latin words "supra" meaning "above", and "sternal" which refers to the sternum or breastbone. The term "Fossa Jugularis Sterni" is also Latin, with "fossa" meaning "ditch" or "trench", "jugularis" referring to the jugular vein, and "sterni" again referring to the sternum.

Anatomy

The Suprasternal Notch is located at the superior end of the sternum, between the left and right clavicle. It is a visible dip and can be easily felt. The notch is an important anatomical landmark as it provides a central point of reference for measuring the body's symmetry and for medical procedures.

Clinical Significance

The Suprasternal Notch is used as a reference point in many medical procedures. For example, it is used to measure the jugular venous pressure, which can provide important information about the functioning of the right side of the heart. It is also used as a landmark for tracheal intubation, a procedure in which a tube is inserted into the trachea to provide a clear airway.
