1. Where are the deep inguinal lymph nodes located?

In the proximal thigh, deep to the fascia lata and alongside the femoral vein.

2. Which major blood vessel is the principal landmark for the deep inguinal lymph nodes?

The femoral vein.

3. What is the usual position of the deep inguinal lymph nodes relative to the femoral vein?

They lie mainly medial to the femoral vein.

4. Which fascial layer separates the deep inguinal nodes from the superficial inguinal nodes?

The fascia lata.

5. How many deep inguinal lymph nodes are typically present?

Usually about three to five, although the number varies.

6. Which deep inguinal lymph node occupies the femoral canal near the femoral ring?

The node of Cloquet, also called Rosenmuller's node.

7. What is the position of the node of Cloquet within the deep inguinal group?

It is the most superior deep inguinal lymph node.

8. What anatomical structure forms the superior opening of the femoral canal?

The femoral ring.

9. Which major lymph node group sends efferent vessels to the deep inguinal nodes?

The superficial inguinal lymph nodes.

10. Which lymphatic vessels from the lower limb drain directly into the deep inguinal nodes?

Deep lymphatic vessels accompanying the major deep blood vessels of the lower limb.

11. Which lymph nodes commonly receive lymph from the lateral foot and posterolateral leg before it reaches the deep inguinal nodes?

The popliteal lymph nodes.

12. Which external genital structures drain primarily to the deep inguinal lymph nodes?

The glans penis and glans clitoris.

13. Which pelvic lymph node group receives efferent vessels from the deep inguinal nodes?

The external iliac lymph nodes.

14. Through which region do efferent lymphatic vessels from the deep inguinal nodes enter the pelvis?

Through the region of the femoral ring beneath the inguinal ligament.

15. Which lymph node group generally follows the deep inguinal nodes in the lymphatic drainage pathway toward the lumbar trunks?

The external iliac lymph nodes.

16. Which major artery supplies the region containing the deep inguinal lymph nodes?

The femoral artery, through local branches.

17. Which venous system drains blood from the deep inguinal lymph node region?

The femoral venous system.

18. What is the main functional distinction between superficial and deep inguinal lymph nodes?

Superficial nodes receive mainly superficial drainage, while deep nodes receive deep drainage and efferents from superficial nodes.

19. Why are deep inguinal lymph nodes important in the spread of malignancy?

They can receive metastatic cells from lower limb and selected external genital lymphatic territories.

20. Why is the node of Cloquet clinically relevant during inguinal lymph node dissection?

It marks the superior extent of the deep inguinal nodal group near the femoral canal.

21. What complication can follow surgical removal of deep inguinal lymph nodes?

Lower limb lymphedema due to disruption of lymphatic drainage.

22. Why must the femoral vein be carefully protected during deep inguinal lymph node surgery?

The nodes lie immediately adjacent to the vein, creating a risk of vascular injury.
