JUGULAR NOTCH Meaning and
Definition
-
The jugular notch is a prominent anatomical feature located in the upper aspect of the sternum, known as the "breastbone," which lies in the center of the chest between the clavicles. It is a V-shaped depression or indentation in the superior part of the manubrium, the uppermost segment of the sternum. This depression is positioned just above the sternal angle, where the manubrium meets the body of the sternum.
The jugular notch is easily recognizable due to its concave shape and distinctive V-like appearance. This anatomical landmark is named after its anatomical proximity to the jugular vein, a major blood vessel in the neck responsible for carrying deoxygenated blood from the head to the heart.
This notch plays a crucial role in various medical procedures and assessments. For instance, during cardiopulmonary resuscitation (CPR), the jugular notch is often used as a landmark for proper hand placement during chest compressions. Additionally, it is an important point of reference for thoracic surgeries, where incisions to access the mediastinum or the structures beneath the sternum may be made.
In summary, the jugular notch is an easily identifiable hollow or indentation found at the superior portion of the sternum. Its prominence and consistent location make it an essential anatomical landmark for medical interventions and assessments relating to the chest and heart region.

Etymology of JUGULAR NOTCH
The term "jugular notch" can be broken down into two parts: "jugular" and "notch".
The word "jugular" originates from the Latin word "jugulum", which means "throat" or "collarbone". In anatomy, the term refers to the veins that transport blood from the head and neck back to the heart. The jugular veins are located in the neck area, near the throat.
The word "notch" comes from the Middle English word "noche", which was derived from the Old English word "cnocc". It refers to a cut or indentation in a surface. In terms of anatomy, a "notch" often refers to a depression or indentation in a bone or other bodily structure.
Therefore, the term "jugular notch" refers to a depression or indentation located at the base of the throat near the collarbone.
