Final answer:
The statement is false; costotransverse joints are found at the articulations between ribs and thoracic vertebrae, not exclusively on ribs.
Step-by-step explanation:
The statement about costotransverse joints is false. Costotransverse joints are indeed found in association with ribs, but they are not exclusive to ribs alone. These joints are formed where the tubercle of the rib articulates with the transverse process of a thoracic vertebra. It's essential to understand the anatomy of the ribs for this topic. The rib cage is part of the thoracic cage, which includes true ribs (1-7) that attach directly to the sternum via their costal cartilage. In contrast, false ribs (8-12) attach indirectly or not at all, with the floating ribs (11-12) not attaching to the sternum. Given this anatomy, it is clear that costotransverse joints occur where ribs articulate with thoracic vertebrae, not exclusively on ribs.
