which of the following is true regarding the cartilage of the larynx?

Options

A. 3 paired and 3 unpaired
B. 4 paired and 2 unpaired
C. 6 paired and 1 unpaired
D. 2 unpaired and 2 paired

Answer

To solve the question regarding the cartilage of the larynx, we need to analyze the options provided and determine which statement is true based on the anatomy of the larynx.

### Step-by-Step Solution:

1. **Understand the Structure of the Larynx**:
- The larynx, commonly known as the voice box, is located in the anterior neck and plays a crucial role in the respiratory system, phonation, and protecting the airway during swallowing.

2. **Identify the Cartilages Present in the Larynx**:
- The larynx is supported by a total of **nine cartilages**. These are divided into paired and unpaired cartilages.

3. **Classify the Cartilages**:
- **Paired Cartilages**: There are three pairs of cartilages, which means there are a total of six paired cartilages:
- Arytenoid Cartilage (2)
- Corniculate Cartilage (2)
- Cuneiform Cartilage (2)
- **Unpaired Cartilages**: There are three unpaired cartilages:
- Thyroid Cartilage (1)
- Cricoid Cartilage (1)
- Epiglottis (1)

4. **Count the Total Number of Cartilages**:
- Total paired cartilages = 3 pairs = 6 cartilages
- Total unpaired cartilages = 3
- Therefore, the total number of cartilages in the larynx = 6 (paired) + 3 (unpaired) = 9.

5. **Evaluate the Options**:
- The options provided are:
- 3 paired and 3 unpaired
- 4 paired and 2 unpaired
- 6 paired and 1 unpaired
- 2 unpaired and 2 unpaired
- From our classification, the correct statement is **3 paired and 3 unpaired**.

6. **Conclusion**:
- The correct answer to the question is **3 paired and 3 unpaired**.
