Elastic laryngeal cartilage are all ,except(NEET/DNB Pattern)
## **Core Concept**
The question tests knowledge of laryngeal cartilages, specifically their composition and classification. Laryngeal cartilages can be made of hyaline cartilage, elastic cartilage, or a combination of both. Understanding the types of cartilage in the larynx is crucial for knowledge of its structure and function.
## **Why the Correct Answer is Right**
The correct answer, **Epiglottis**, is made of elastic cartilage. Other structures in the larynx, like the arytenoids, corniculate cartilages, and cuneiform cartilages, are also made of elastic cartilage. However, the thyroid cartilage, cricoid cartilage, and most of the tracheal cartilages are made of hyaline cartilage.
## **Why Each Wrong Option is Incorrect**
- **Option A:** The **Arytenoids** are indeed made of elastic cartilage, which makes them crucial for voice production by controlling the tension of the vocal cords.
- **Option B:** The **Corniculate cartilages** are also made of elastic cartilage and are part of the laryngeal skeleton, providing support to the arytenoid cartilages.
- **Option D:** The **Cuneiform cartilages** are made of elastic cartilage as well and are located within the aryepiglottic folds.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the **thyroid cartilage**, which is the largest cartilage of the larynx and forms the Adam's apple, is made of **hyaline cartilage**, not elastic cartilage. This is a crucial distinction for anatomical and clinical purposes.
## **Correct Answer:** . **Thyroid cartilage**
