Answer
True ribs only connect directly to the sternum by way of costal cartilage.
Solution
To solve this problem, we need to understand the classification of ribs in relation to their connection to the sternum.
1. **True Ribs**: These are the first seven pairs of ribs (ribs 1-7) that connect directly to the sternum via their own costal cartilage.
2. **False Ribs**: These include ribs 8-10, which do not connect directly to the sternum but are attached to the costal cartilage of the rib above them.
3. **Floating Ribs**: These are ribs 11 and 12, which do not connect to the sternum at all.
Given this classification, the only type of rib that connects directly to the sternum by way of costal cartilage is the **True Ribs**.
Thus, the correct answer is **True ribs only**.

The correct answer is true ribs only! These ribs are the first seven pairs that attach directly to the sternum through individual costal cartilage, providing a rigid structure that allows for protection of vital organs and flexibility for the ribcage during breathing. Interestingly, the true ribs are often the unsung heroes of the ribcage. They not only shield the heart and lungs from external impacts but also play a crucial role in respiratory mechanics. Their direct attachment to the sternum allows for optimal expansion and contraction during the inhalation and exhalation process, making them essential for efficient breathing!
