Sertoli cells are found in

Options

A. testis of cockroach
B. liver of mammals
C. testis of mammals
D. testis of frog

Answer

**Step-by-Step Solution:**

1. **Understanding Sertoli Cells**: Sertoli cells are a type of somatic cell found in the seminiferous tubules of the testes. They play a crucial role in the process of spermatogenesis, which is the production of sperm.

2. **Evaluating the Options**: The question provides four options:
- A) Testis of Cockroach
- B) Liver of Mammals
- C) Testis of Mammals
- D) Testis of Frogs

3. **Analyzing Each Option**:
- **Option A (Testis of Cockroach)**: Sertoli cells are not found in insects like cockroaches. They are specific to vertebrates, particularly mammals.
- **Option B (Liver of Mammals)**: The liver does not contain Sertoli cells. This organ is involved in metabolism and detoxification, not in spermatogenesis.
- **Option C (Testis of Mammals)**: This is the correct option. Sertoli cells are indeed found in the testes of mammals, specifically within the seminiferous tubules where sperm development occurs.
- **Option D (Testis of Frogs)**: While frogs are amphibians, they do not have Sertoli cells as seen in mammals. Their reproductive structures differ significantly.

4. **Conclusion**: Based on the analysis, the only option that correctly identifies the location of Sertoli cells is **Option C (Testis of Mammals)**.

5. **Final Answer**: Sertoli cells are found in the **Testis of Mammals** (Option C).
