STERNAL NOTCH Meaning and
Definition
-
The sternal notch, also known as the jugular notch or suprasternal notch, is a distinct anatomical feature located at the superior part of the sternum, or breastbone. It is a V-shaped depression or indentation that can be felt and observed on the anterior aspect of the thorax. The term "sternal" refers to the sternum, while "notch" describes a depression or indentation in bone.
The sternal notch serves as an important landmark for anatomical reference and clinical examination. It is specifically used to locate and identify other structures or landmarks in the body. For instance, when performing cardiopulmonary resuscitation (CPR), the sternal notch is a crucial point for determining the proper hand placement for chest compressions.
Additionally, the sternal notch is utilized for measuring or assessing various anatomical dimensions. It aids in determining the size of the thoracic cavity, particularly when considering lung capacity, or when assessing deviations from normal anatomical measurements. It also assists in clinical evaluations such as assessing neck positioning or palpating the carotid pulse.
Overall, the sternal notch plays a key role in both anatomical and clinical contexts. Its prominence and distinctiveness make it a valuable reference point and aid to accurately locate, measure, and examine various structures in the thoracic region.
