The correct Answer is:
To solve the question regarding the components of the interstitial spaces outside the seminiferous tubules, we can follow these steps: ### Step-by-Step Solution 1. **Understand the Structure**: The seminiferous tubules are located within the testes and are responsible for sperm production. The area surrounding these tubules is known as the interstitial space. 2. **Identify the Components of Interstitial Spaces**: The interstitial spaces contain various structures and cells. Common components found in these spaces include: - Blood vessels - Immunologically competent cells - Leydig cells (not lytic cells as mentioned in the transcript) - Sertoli cells (which are actually located inside the seminiferous tubules) 3. **Analyze the Options**: The question provides four options: - Blood vessels - Immunologically competent cells - Leydig cells (likely intended instead of "lytic cells") - Sertoli cells 4. **Determine the Incorrect Option**: - Blood vessels, immunologically competent cells, and Leydig cells are indeed found in the interstitial spaces. - Sertoli cells, however, are located within the seminiferous tubules and not in the interstitial spaces. 5. **Conclusion**: Therefore, the correct answer to the question "The region outside the seminiferous tubules is called interstitial spaces which contain all, except..." is **Sertoli cells**. ### Final Answer **Sertoli cells** ---
