Lining of sebaceous duct is composed of : -

Options

A. Cuboidal statified Epithelium
B. Startified squamous
C. Simple columnar
D. Simple squamous

Answer

To determine the lining of the sebaceous duct, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of Sebaceous Glands**:
- Sebaceous glands are responsible for secreting oily substances (sebum) that help lubricate and protect the skin.

2. **Identify the Types of Epithelium**:
- The options given are:
- Cuboidal stratified epithelium
- Stratified squamous epithelium
- Simple columnar epithelium
- Simple squamous epithelium

3. **Analyze the Structure of Sebaceous Ducts**:
- Sebaceous ducts are the channels through which the sebum is transported from the sebaceous glands to the skin surface.

4. **Determine the Appropriate Epithelium Type**:
- **Cuboidal Stratified Epithelium**: This type consists of multiple layers of cuboidal cells, which is suitable for ducts that require protection and flexibility.
- **Stratified Squamous Epithelium**: Typically found in areas subject to abrasion, like the skin.
- **Simple Columnar Epithelium**: Found in the digestive tract.
- **Simple Squamous Epithelium**: Found in areas requiring diffusion, such as the lungs and blood vessels.

5. **Conclusion**:
- The lining of the sebaceous duct is composed of **cuboidal stratified epithelium**. This type of epithelium provides the necessary protection and structural integrity for the duct.

### Final Answer:
The lining of the sebaceous duct is composed of **cuboidal stratified epithelium**.
