Which of the following are present in germinal epithelium of seminiferous tubules?

Options

A. Sertoli cells
B. Leydig's cells
C. Antral cells
D. Follicular cells

Answer

To answer the question regarding which cells are present in the germinal epithelium of seminiferous tubules, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Germinal Epithelium**:
- The germinal epithelium is a thin layer of cells that lines the seminiferous tubules in the testes. It is responsible for the production of sperm.

2. **Identifying Key Cell Types**:
- Within the germinal epithelium, there are various types of cells involved in spermatogenesis (the process of sperm formation). The primary cell types include:
- **Sertoli Cells**: These cells are crucial for nourishing developing sperm cells and supporting their maturation.
- **Spermatocytes**: These are the cells that undergo division to eventually form sperm. They include primary and secondary spermatocytes.

3. **Sertoli Cells Function**:
- Sertoli cells provide structural and nutritional support to the developing sperm cells. They are essential for the process of spermatogenesis.

4. **Other Cell Types**:
- While Leydig cells (which produce testosterone) are important in the male reproductive system, they are located outside the seminiferous tubules, not within the germinal epithelium.

5. **Conclusion**:
- Based on the above information, the correct answer to the question is that **Sertoli cells** are present in the germinal epithelium of seminiferous tubules.

### Final Answer:
The cells present in the germinal epithelium of seminiferous tubules are **Sertoli cells**.
