The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Rib Structure**: - The human rib cage consists of a total of 12 pairs of ribs. These ribs are attached to the vertebrae at the back and to the sternum at the front. 2. **Classification of Ribs**: - Ribs are classified into three categories: - **True Ribs**: The first 7 pairs of ribs that connect directly to the sternum via hyaline cartilage. - **False Ribs**: The next 3 pairs (8th, 9th, and 10th ribs) that do not connect directly to the sternum but are attached to the cartilage of the ribs above them. - **Floating Ribs**: The last 2 pairs (11th and 12th ribs) that do not connect to the sternum at all. 3. **Identifying False Ribs**: - Since the question asks about false ribs, we focus on the 3 pairs of ribs that are classified as false ribs. These are the ribs that do not connect directly to the sternum. 4. **Conclusion**: - Therefore, false ribs are defined as the 3 pairs of ribs that are located after the first 7 pairs of true ribs. ### Final Answer: False ribs are the 3 pairs of ribs that are located after the first 7 pairs of true ribs. ---
