Question

The combining form thorac/o means the thorax (or chest). As with other vertebrae, the thorac+ic vertebrae are so named because of their location. They are numbered T1 through T12. The thoracic vertebrae are part of the posterior (back) wall of the _____ cavity.

Answer 1

The thoracic vertebrae form part of the posterior wall of the thoracic cavity, which protects the heart and lungs.

Step-by-step explanation:

The thoracic vertebrae contribute to the structure of the thoracic cage, also known as the rib cage, which includes the ribs, sternum, thoracic vertebrae, and costal cartilages.

This cage is crucial for protecting vital organs; specifically, the thoracic vertebrae are part of the posterior (back) wall of the thoracic cavity. The thoracic cavity houses important organs, such as the heart and lungs, and is shielded by the thoracic cage. It consists of the ribs, sternum, thoracic vertebrae, and costal cartilages.
