The superficial inguinal lymph nodes are divided into horizontal and vertical groups. The vertical group receives lymph chiefly from:
- A Lower limb via the great saphenous territory ✓
- B Perineum and external genitalia
- C Anterior abdominal wall below the umbilicus
- D Gluteal region and lower back
Correct answer: A. Lower limb via the great saphenous territory
Explanation
The vertical group runs along the terminal part of the great saphenous vein and drains the superficial tissues of the entire lower limb. The horizontal group, arranged below the inguinal ligament, drains the perineum, external genitalia, buttock, and the anterior abdominal wall below the umbilicus. All superficial inguinal efferents pass through the saphenous opening to reach the deep inguinal and then external iliac nodes.
