Which type of rib connects directly to the sternum by way of costal cartilage? True ribs only True and false ribs Floating ribs only False 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!
