The type of epithelial cells which line the inner surface of Fallopian tubes, bronchioles and small bronchi are known as

Options

A. squamous epthelium
B. ciliated epithelium
C. columnar epithelium
D. cubical epithelium

Answer

To solve the question regarding the type of epithelial cells that line the inner surface of the Fallopian tubes, bronchioles, and small bronchi, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Epithelial Cells**:
- Epithelial cells are classified into different types based on their shape and arrangement. The main types include squamous, cuboidal, and columnar.

2. **Identifying the Types**:
- **Squamous Epithelium**: These cells are flat and scale-like, resembling pavement.
- **Cuboidal Epithelium**: These cells are cube-shaped.
- **Columnar Epithelium**: These cells are taller and slender, with nuclei usually located at the base.

3. **Recognizing Ciliated Epithelium**:
- Columnar epithelial cells can have cilia on their surface. When they do, they are referred to as **ciliated columnar epithelium**.

4. **Locating the Specific Organs**:
- The question specifies the Fallopian tubes, bronchioles, and small bronchi. These organs are known to have ciliated columnar epithelium lining their inner surfaces.

5. **Conclusion**:
- Therefore, the type of epithelial cells that line the inner surface of the Fallopian tubes, bronchioles, and small bronchi is called **ciliated columnar epithelium**.

### Final Answer:
Ciliated columnar epithelium.
