Sternum Anatomy

The manubrium is the widest and thickest part of the sternum, providing a strong structural base.
The jugular notch is the easily palpated concave center located at the superior border of the manubrium, serving as an important anatomical landmark.
The body of the sternum is longer, narrower, and thinner compared to the manubrium, functioning as the central part that contributes to the sternum's overall length.
The body of the sternum is located at the T5 to T8 vertebral levels, which is important for anatomical orientation.
Five sternebrae are typically obvious in young people, representing the segments that make up the sternum during development.
The xiphoid process is the smallest and most variable part of the sternum, often differing greatly in shape and size among individuals.
Sternebrae begin to fuse from the inferior end during late adolescence, indicating the maturation of the sternum.
In young people, the xiphoid process is primarily made of hyaline cartilage, which may ossify over time.
The xiphoid process also indicates the location of the diaphragm and is an important reference point in the median plane for various medical procedures.
The infrasternal angle, formed by the costal margins, is the site of convergence of the lower ribs, important for examining respiratory mechanics and conditions.
