Neither the trachea nor the bronchi contain.

Options

A. (1) hyaline cartilage
B. (2) goblet cells
C. (3) ciliated columnar epithelium
D. (4) simple squamous epithelium

Answer

To answer the question "Neither the trachea nor the bronchi contain," we need to analyze the components listed in the options: hyaline cartilage, goblet cells, ciliated columnar epithelium, and simple squamous epithelium.

### Step-by-Step Solution:

1. **Identify the Structures in the Trachea and Bronchi**:
- The trachea and bronchi are parts of the respiratory system that help in conducting air to the lungs.
- They are lined with specific types of cells and tissues that serve various functions.

2. **Examine Hyaline Cartilage**:
- The trachea contains C-shaped rings of hyaline cartilage that provide structural support and keep the airway open.
- The bronchi also contain hyaline cartilage, but in the form of irregular plates.

3. **Examine Goblet Cells**:
- Goblet cells are present in the trachea and bronchi. They secrete mucus, which helps trap dust and pathogens, preventing them from entering the lungs.

4. **Examine Ciliated Columnar Epithelium**:
- Ciliated columnar epithelium is found in the trachea and bronchi. The cilia help move mucus and trapped particles out of the airways.

5. **Examine Simple Squamous Epithelium**:
- Simple squamous epithelium is not found in the trachea or bronchi. This type of epithelium is typically found in areas where diffusion occurs, such as the alveoli in the lungs.

6. **Conclusion**:
- Therefore, the correct answer to the question is that neither the trachea nor the bronchi contain **simple squamous epithelium**.

### Final Answer:
Neither the trachea nor the bronchi contain **simple squamous epithelium**.
