The jugular notch is a significant anatomical feature of the sternum.
Defining the Jugular Notch
The jugular notch, also known as the suprasternal or presternal notch, is the easily felt indentation located at the top of the breastbone, or sternum. It's more technically described as the large indentation found along the superior border of manubrium of the sternum. This notch is a palpable, or noticeable by touch, depression situated at the base of your neck.
Location and Anatomical Significance
- Superior Manubrium: The jugular notch is specifically located on the manubrium, the uppermost part of the sternum.
- Between Clavicular Notches: It lies directly between the right and left clavicular notches, where the collarbones (clavicles) attach to the sternum.
- Palpable Depression: The notch is easily felt as a depression at the root of the neck, making it a useful landmark for medical professionals.
Practical Applications
The jugular notch serves several important functions:
- Anatomical Landmark: It is a common reference point for physical examinations, surgical procedures, and medical imaging, allowing medical professionals to precisely locate structures of the chest and neck.
- Respiratory Assessment: The position of the trachea, the windpipe, can be estimated by palpating this notch.
- Central Line Insertion: The notch is often used to guide the insertion of central lines, which provide direct access to large veins.
