At which vertebral level is the jugular notch located?

The jugular notch, also known as the suprasternal notch, is a prominent anatomical feature located at the upper part of the sternum between the clavicles. This notch is specifically correlated with the vertebral levels of T2 and T3. When locating the jugular notch on a patient or anatomical model, it is important to note that it aligns with the T2-T3 intervertebral disc.

In terms of clinical relevance, identifying the jugular notch is crucial for procedures such as central venous catheterization and for anatomical orientation during physical examinations. The precise location provides a guide to the underlying structures and blood vessels in the neck and thorax.

The other vertebral level options do not accurately match the anatomical position of the jugular notch, as they correspond to different regions of the thoracic spine and would not provide the same clinical landmarks needed for various medical procedures.
