In which of the following combination, both components have hyaline cartilage?
- A. Epiglottis & intervertebral disc
- B. Trachea & intervertebral disc
- C. Nose & pinna
- D. Nose & trachea
Explanation
The C shaped rings of the trachea and the supporting plates of the nose are both hyaline cartilage, the smooth glassy type that also covers the ends of bones. The intervertebral discs are fibrocartilage, built for shock absorption, and the epiglottis and pinna are elastic cartilage, which springs back into shape. Each pairing in the wrong options mixes two different types.
