Costa of the 7th rib
Explanation:
- In the sternal rib cage, ribs 1 through 7 which have their own cartilage are attached directly to the sternum, so are referred true ribs.
- The costal cartilages of the ribs 8 to 10 are only attached to the 7th rib and are called as the false ribs.
- Also called vertebrochondral ribs, they are cartilaginous and the elasticity of the false ribs helps expansion of the sternal cage to increase the intake capacity of the lungs during inhalation.
