The correct Answer is:
To determine the number of vertebrochondral ribs in humans, we can follow these steps: ### Step 1: Understand the Definition Vertebrochondral ribs, also known as false ribs, are those ribs that do not attach directly to the sternum. Instead, they connect to the sternum indirectly through the costal cartilages of the ribs above them. ### Step 2: Identify the Ribs In humans, the ribs are categorized as follows: - True ribs (1-7): Directly attached to the sternum. - Vertebrochondral ribs (8-10): Indirectly attached to the sternum via the costal cartilages. - Floating ribs (11-12): Do not attach to the sternum at all. ### Step 3: Count the Vertebrochondral Ribs The vertebrochondral ribs are specifically ribs 8, 9, and 10. Therefore, there are three pairs of vertebrochondral ribs. ### Step 4: Conclusion Thus, the total number of vertebrochondral ribs in humans is 6 (3 pairs). ### Final Answer The number of vertebrochondral ribs in humans is **6**. ---
