Sertoli cells occur:

Options

A. Between the seminiferous tubules
B. In germinal epithelium of seminiferous tubules
C. In upper part of fallopian tubes
D. In germinal epithelium of ovary

Answer

**Step-by-Step Solution:**

1. **Understanding Sertoli Cells**: Sertoli cells, also known as nurse 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 where sperm production occurs.

3. **Function of Sertoli Cells**: Besides providing nutrition to developing sperm, Sertoli cells also secrete hormones such as inhibin, which plays a role in regulating the production of follicle-stimulating hormone (FSH).

4. **Identifying the Correct Option**: Based on the information provided, Sertoli cells are not found in the middle of the seminiferous tubules, nor are they located in the fallopian tubes or the epithelium of the ovary. The correct answer is that Sertoli cells occur in the germinal epithelium of the seminiferous tubules.

5. **Conclusion**: Therefore, the correct answer to the question "Where do Sertoli cells occur?" is that they are found in the germinal epithelium of the seminiferous tubules.
