MANUBRIUM STERNI Meaning and
Definition
-
Manubrium sterni is a Latin term referring to the uppermost segment of the sternum, commonly known as the breastbone. It is a vital component of the human skeletal system, located in the central part of the chest, connecting the two clavicles and forming the superior portion of the sternum. The word "manubrium" is derived from the Latin term "manubrius," meaning handle or grip, and "sterni" pertains to the sternum.
Anatomically, the manubrium sterni has a prominent thick and triangular shape with a slight concavity. It serves as an attachment site for several important structures including the clavicles, first two pairs of ribs, and the costal cartilages of the second and third ribs. Additionally, it plays a crucial role in protecting internal organs, such as the heart and major blood vessels in the thoracic cavity.
The manubrium sterni can be divided into various anatomical landmarks including the jugular notch, a shallow depression at the top of the manubrium, which can be easily palpated. It also has two clavicular notches, one on each side, where the clavicles articulate. Furthermore, it connects to the body of the sternum, forming an angle known as the sternal angle or angle of Louis.
Understanding the anatomy of the manubrium sterni is essential in medical fields such as surgery, radiology, and anatomy education. In certain pathological conditions or trauma, the manubrium sterni can be fractured or dislocated, leading to complications that may require medical intervention.

Etymology of MANUBRIUM STERNI
The word "manubrium sterni" has its etymology derived from Latin.
The term "manubrium" comes from the Latin word "manubrius", meaning "handle" or "hilt". It refers to the handle-like shape of the uppermost part of the sternum (breastbone) in humans and some animals.
"Sterni" is the genitive form of "sternum", which means "breastbone" in Latin. The word is thought to be derived from the Proto-Indo-European root "stḗr", which means "chest" or "breast".
Combined, "manubrium sterni" literally translates to "handle of the breastbone", describing the anatomical structure at the upper part of the sternum.
