Which term refers to the group of bones forming the thoracic cavity of the chest?

• A. Thoracic Cage
• B. Clavicle
• C. Humerus
• D. Sacrum

Answer: (A)

The main idea here is naming the bony framework that encloses the chest. The group of bones forming the thoracic cavity is the thoracic cage. It includes the ribs, sternum, and the thoracic vertebrae, creating the protective enclosure for the heart and lungs and providing attachment points for muscles involved in breathing. The clavicle and humerus are parts of the shoulder and arm, not the chest’s bony enclosure, and the sacrum belongs to the pelvis. So, the term that best describes the bones forming the chest cavity is the thoracic cage.
