The germinal epithelium of mammalian ovary is lined by  

Options

A. squamous epithelium .
B. cuboidal epithelium
C. columnar epithelium
D. pseudo stratified epithelium

Answer

To answer the question "The germinal epithelium of mammalian ovary is lined by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Germinal Epithelium**:
- The germinal epithelium is a layer of cells that covers the surface of the ovary in mammals. It plays a crucial role in the development of ovarian follicles.

2. **Identifying Epithelial Types**:
- The options provided are:
- Squamous epithelium
- Cuboidal epithelium
- Columnar epithelium
- Pseudostratified epithelium

3. **Analyzing the Structure**:
- The germinal epithelium is primarily composed of simple epithelial cells. In mammals, this layer is typically made up of cuboidal epithelial cells.

4. **Functions of the Germinal Epithelium**:
- The germinal epithelium serves several functions, including:
- **Secretion**: Producing hormones and other substances.
- **Absorption**: Taking in nutrients and other necessary substances.
- **Protection**: Providing a protective barrier for the underlying tissues.

5. **Conclusion**:
- Based on the analysis, the germinal epithelium of the mammalian ovary is lined by **cuboidal epithelium**.

### Final Answer:
The germinal epithelium of the mammalian ovary is lined by **cuboidal epithelium**.
