Sertoli cells are found in :

Options

A. Pancreas and secrete cholecystokinin
B. Ovaries and secrete progesterone
C. Adrenal cortex and secrete adrenaline
D. Seminiferous tubules and provide nutrition to germ cells

Answer

**Step-by-Step Solution:**

1. **Understanding Sertoli Cells**: Sertoli cells are specialized cells found in the male reproductive system. Their primary function is to support and nourish developing sperm cells (spermatozoa).

2. **Location of Sertoli Cells**: Sertoli cells are located within the seminiferous tubules of the testes. These tubules are the site of sperm production.

3. **Role of Sertoli Cells**: Sertoli cells provide essential nutrients and support to the germ cells (sperm cells) during their development. They create an environment conducive to the maturation of spermatozoa.

4. **Identifying the Correct Answer**: Given the options provided in the question, the correct answer is the seminiferous tubules, as this is where Sertoli cells are found and where they perform their function.

5. **Conclusion**: Therefore, Sertoli cells are found in the seminiferous tubules of the testes.

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