Question: 1 / 400

Which ribs are categorized as false ribs?

Ribs 1-7

Ribs 8-12

False ribs are categorized as those ribs that do not attach directly to the sternum. In human anatomy, ribs 1 through 7 are known as true ribs because they connect directly to the sternum via their own costal cartilages. Ribs 8 through 12 are referred to as false ribs. Among these, ribs 8 to 10 (the upper false ribs) connect to the sternum indirectly through the costal cartilage of the rib above them, while ribs 11 and 12 are classified as floating ribs because they do not attach to the sternum at all.

Ribs 8-12 collectively encompass all false ribs, making this classification significant when studying rib anatomy, chest structure, and thoracic mechanics. Understanding the distinctions between true and false ribs is crucial, particularly in contexts such as trauma assessment or surgical planning, where rib integrity and attachment are important considerations.
