Sternum is the flat bone in the chest.
Location of the sternum
The sternum is a midline chest bone to which the first six ribs are attached. The other ribs are floating.
Structure of the sternum
The sternum is a flat symmetrical bone with three main parts:
- the manubrium, which forms the upper part of the sternum and is attached to the clavicles and first pair of ribs;
- the body of the sternum to which the next five ribs are attached;
- and the xyphoid process which ends in a point at the bottom of the sternum.
Function of the sternum
The function of the sternum is to strengthen the ribs and act as an attachment site for intercostal muscles.
The sternum is located in the chest and is the attachment point for the ribs and intercostal muscles. © DR
