What is jugular notch?

The jugular notch, also known as the suprasternal notch or supraclavicular notch, is an indentation located at the upper part of the sternum, between the two clavicles. It is easily visible and palpable on the neck when looking straight ahead.

The jugular notch serves as a useful anatomical landmark for locating important structures in the neck and chest region. It is commonly used as a reference point for procedures such as central venous catheterization, tracheostomy placement, and chest compressions during CPR.

In terms of clinical significance, the jugular notch is located at the level of the T2/T3 vertebrae, making it a reliable reference point for estimating the level of the thoracic spine during physical exams and imaging studies. Additionally, the jugular notch can be used to assess a patient's respiratory effort and to determine the position of the trachea.

Overall, the jugular notch is an important anatomical feature that plays a crucial role in clinical assessments and procedures involving the neck and chest regions.
