Which term is synonymous with the chest?

• A. Face
• B. Pelvis
• C. Thorax
• D. Abdomen

Answer: (C)

In anatomy, the chest refers to the thorax—the region of the trunk between the neck and the abdomen. The thorax is defined by the rib cage (ribs, sternum, and thoracic vertebrae) and houses the heart and lungs, protected within the pleural and pericardial sacs. The diaphragm forms the lower boundary separating it from the abdomen. Because the commonly used word “chest” maps to this central trunk region, the anatomical synonym is the thorax. The other regions listed—face, pelvis, and abdomen—are distinct areas: the face is part of the head, the pelvis is the lowermost portion of the trunk, and the abdomen lies below the thorax containing digestive organs.
