Jugular Notch Of The Sternum, Posterior View

Description

Jugular (suprasternal) notch crowns the superior border of the manubrium sterni, seen from the posterior aspect as a midline concavity between the right and left clavicular notches. From this fixed posterior perspective, the internal surface of the manubrium slopes inferiorly toward the manubriosternal junction, with the shallow impressions for the first costal cartilages positioned inferolaterally near the superior sternal body. Medial alignment is emphasized: the notch lies on the midsagittal plane, while the clavicular facets sit laterally and slightly superior to the first costal notches. A palpable landmark. Clinically, the jugular notch anchors surface anatomy of the thoracic inlet and helps orient procedures that rely on accurate midline localization, including low cervical tracheostomy planning, suprasternal access for mediastinal palpation, and placement of central venous lines where clavicular and sternal landmarks guide needle trajectory toward the internal jugular or subclavian vein. Posterior viewing clarifies how the manubrium forms the anterior boundary of the superior mediastinum and why retrosternal goiter, mediastinal masses, or hematoma after blunt trauma can relate spatially to this region. The lighting and bony relief in this illustration support teaching of manubrial anatomy without distraction from soft tissues. Use this illustration in gross anatomy and radiologic anatomy courses to pair surface landmarks with CT correlations at the thoracic inlet, and in surgical education materials that discuss cervicothoracic approaches, manubrial fractures, or sternoclavicular joint alignment. It also fits orthopedic and emergency medicine publications where precise terminology (jugular notch versus clavicular notch) prevents common labeling errors.
