Which of the following laryngeal cartilage is hyaline –
**Core Concept**
The larynx is composed of several cartilages, each with distinct types, including hyaline, elastic, and fibrocartilage. **Hyaline cartilage** is a type of cartilage that provides support and maintains the shape of the laryngeal structure.
**Why the Correct Answer is Right**
The correct answer, which corresponds to the **cricoid cartilage**, is made of **hyaline cartilage**. This is because the cricoid cartilage, being a ring-shaped structure, requires the rigidity and support that hyaline cartilage provides to maintain the airway open.
**Why Each Wrong Option is Incorrect**
**Option A:** Is incorrect because the epiglottis is made of **elastic cartilage**, allowing for flexibility.
**Option B:** Is incorrect as it does not correspond to the correct laryngeal cartilage made of hyaline cartilage.
**Option D:** Is also incorrect as it is not the specific cartilage made of hyaline cartilage.
**Clinical Pearl / High-Yield Fact**
Remember, the **cricoid cartilage** is the only complete ring in the airway, and its hyaline nature is crucial for maintaining airway patency.
**Correct Answer:** Correct Answer: C. Cricoid cartilage.
