Epiglottis is composed of :-

Options

A. Hyaline cartilage
B. White fibro cartilage
C. Both
D. Elastic cartilage

Answer

**Step-by-Step Solution:**

1. **Understanding the Epiglottis**: The epiglottis is a flap-like structure located at the root of the tongue. Its primary function is to prevent food and liquid from entering the trachea during swallowing.

2. **Identifying the Composition**: To answer the question about what the epiglottis is composed of, we need to look into its anatomical structure.

3. **Recognizing the Type of Cartilage**: The epiglottis is primarily made up of elastic cartilage. This type of cartilage is known for its flexibility and resilience.

4. **Characteristics of Elastic Cartilage**: Elastic cartilage contains a network of elastic fibers along with collagen fibers. The presence of these fibers allows the epiglottis to bend and return to its original shape, which is crucial for its function.

5. **Comparison with Other Cartilages**: While elastic cartilage is histologically similar to hyaline cartilage, it is distinguished by the presence of yellow elastic fibers, which contribute to its flexibility.

6. **Conclusion**: Therefore, we conclude that the epiglottis is composed of elastic cartilage, also referred to as yellow cartilage.

**Final Answer**: The epiglottis is composed of elastic cartilage.
