The correct Answer is:
To determine which cells line the inside of each seminiferous tubule, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Structure of Seminiferous Tubules**: - Seminiferous tubules are the functional units of the testes, responsible for the production of sperm. 2. **Identify the Types of Cells Present**: - Within the seminiferous tubules, there are two main types of cells: - **Male Germ Cells**: These are the primordial germ cells that develop into sperm cells (spermatogonia). - **Sertoli Cells**: These cells, also known as nurse cells, support and nourish the developing sperm. 3. **Differentiate Between Cell Types**: - **Leydig Cells** (or interstitial cells) are located outside the seminiferous tubules in the interstitial space and are responsible for producing testosterone. They do not line the inside of the tubules. - **Interstitial Cells**: These are synonymous with Leydig cells and are also not found lining the tubules. 4. **Conclusion**: - The cells that line the inside of the seminiferous tubules are the **Sertoli Cells** and **Male Germ Cells**. However, since the question specifically asks for the cells that line the inside, the correct answer is **D. Sertoli Cells**. ### Final Answer: **D. Sertoli cells** ---
