Sertoli cells are found in

Options

A. Pancres and secrete cholecystokinin
B. Ovaries and secrete progesterone
C. Adrenal cortex and secrete adrenaline
D. Seminiferous tubules and secrete ABP and inhibin

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks where Sertoli cells are found.

2. **Understand Sertoli Cells**: Sertoli cells are somatic cells located in the testis. They play a crucial role in the male reproductive system.

3. **Locate the Options**: The options provided include:
- Pancreas (secretes cholecystokinin)
- Ovaries (secrete progesterone)
- Adrenal cortex (secretes adrenaline)
- Seminiferous tubules (secrete androgen-binding protein and inhibin)

4. **Analyze the Options**:
- **Pancreas**: Not related to Sertoli cells.
- **Ovaries**: Related to female reproductive functions, not Sertoli cells.
- **Adrenal Cortex**: Related to adrenal hormones, not Sertoli cells.
- **Seminiferous Tubules**: This is where Sertoli cells are located and function in spermatogenesis.

5. **Confirm the Correct Answer**: Since Sertoli cells are found in the seminiferous tubules and are essential for sperm formation, the correct answer is option D: Seminiferous tubules.

6. **Summarize the Function**: Sertoli cells support the development of sperm cells and secrete substances such as androgen-binding protein (ABP) and inhibin, which are important for regulating spermatogenesis.

**Final Answer**: Sertoli cells are found in the seminiferous tubules.
