Sternal Angle:
- Junction between the manubrium and the body of the sternum.
- Signifies the level of the second rib, crucial for rib counting and thoracic assessments.
Manubrium:
- The uppermost part of the sternum.
- Articulates with the clavicles and first ribs, forming the thoracic skeleton.
Jugular Notch:
- A dip located at the superior border of the manubrium.
- Easily palpable, serves as a landmark for medical examinations.
Clavicular Notch:
- Located on either side of the manubrium.
- Receives the clavicles, forming the sternoclavicular joint important for shoulder mobility.
Body:
- The central portion of the sternum.
- Provides structural support and articulates with multiple ribs via costal cartilages.
