How many true ribs and false ribs are there in total?

• A. 5 true, 7 false
• B. 12 true, 8 false
• C. 7 true, 5 false
• D. 8 true, 4 false

Answer: (C)

The correct answer indicates that there are 7 true ribs and 5 false ribs, which accurately reflects the anatomy of the human rib cage. The human rib cage is made up of a total of 12 pairs of ribs, with the first 7 pairs classified as true ribs and the remaining 5 pairs as false ribs. True ribs are directly attached to the sternum via their costal cartilage, providing them with a stable connection to the midline of the body, which is crucial for protecting vital organs and maintaining structural integrity. The first seven pairs (ribs 1 to 7) are therefore defined as true ribs. False ribs, on the other hand, consist of the last 5 pairs (ribs 8 to 12). These ribs do not have a direct attachment to the sternum. Instead, the 8th, 9th, and 10th ribs are indirectly connected to the sternum through the costal cartilage of the rib above, and the last two pairs (11th and 12th ribs) are classified as floating ribs, as they do not connect to the sternum at all. Thus, understanding the classification of ribs and their anatomical relevance leads to the conclusion that in the human rib
