CLAVICULAR NOTCH Meaning and
Definition
-
The clavicular notch, also known as the suprasternal notch or the jugular notch, is a distinct anatomical feature found in the human body. It is a shallow depression located at the base of the neck, between the clavicles or collarbones, in the superior part of the sternum or breastbone.
To better visualize its position, the clavicular notch can be identified by tracing a line between the medial ends of the clavicles and finding the concave dip at the top of the sternum. On the inside of the clavicular notch lies the thymus gland, which plays a crucial role in immune system development during childhood.
Functionally, the clavicular notch serves as a landmark for various medical assessments. For instance, it aids in locating the sternal angle, the point where the second rib attaches to the sternum, which is important for clinical examinations such as cardiac auscultation. Additionally, the clavicular notch serves as a reference point for determining the position of other anatomical structures in the neck and upper torso.
Overall, the clavicular notch is a crucial anatomical landmark that helps identify anatomical structures and serves as a helpful reference point for various medical assessments and examinations.
