The common name for the sternum is the breastbone. It is a flat bone located at the front center of the chest and connects to the ribs via cartilage, forming part of the ribcage that protects the heart and lungs.
The breastbone has three main parts: the manubrium, the body, and the xiphoid process. The manubrium is the top portion, which connects to the first pair of ribs and is also where the clavicles (collarbones) articulate. The body of the sternum is the elongated middle section, and the xiphoid process is the small, pointed lower section.
Understanding the structure and function of the breastbone is important in anatomy and medicine, as it plays a crucial role in providing support and protection for vital thoracic organs.
