Which of the following ribs are classified as 'true ribs'?

The classification of ribs as 'true ribs' refers specifically to the anatomical structure and their connection to the sternum. True ribs, which are the first seven pairs of ribs (ribs 1 through 7), are characterized by directly attaching to the sternum via their own costal cartilage. This direct connection allows for a more stable and supportive structure within the thoracic cavity, which plays a critical role in protecting vital organs such as the heart and lungs.

The other categories of ribs—such as false ribs, which include ribs 8 through 10 that connect to the sternum indirectly through the cartilage of the rib above, and floating ribs (which are ribs 11 and 12) that do not attach to the sternum at all—highlight the specific characteristics that distinguish true ribs. Understanding these classifications is essential for medical administrative assistants, as it informs everything from patient education to anatomical terminology used in medical documentation.
