Intermediate Superficial Inguinal Nodes Quiz

Q1. How is the horizontal group of superficial inguinal nodes oriented?

• Vertically through the adductor canal
• Approximately parallel to the inguinal ligament
• Along the small saphenous vein
• Along the tibial crest

Q2. How is the vertical group of superficial inguinal nodes arranged?

• Along the terminal great saphenous vein
• Along the sciatic nerve
• Along the iliac crest
• Along the popliteal artery

Q3. Which superficial lower-limb lymphatics commonly follow the great saphenous vein toward the groin?

• Deep pelvic lymphatics
• Lymphatics from the upper limb
• Lymphatics from the medial side of the lower limb
• Thoracic lymphatics

Q4. Where can lymphatics accompanying the small saphenous vein drain before continuing proximally?

• Axillary lymph nodes
• Parasternal lymph nodes
• Popliteal lymph nodes
• Submandibular lymph nodes

Q5. Which external genital skin structures normally drain predominantly to superficial inguinal nodes?

• Prostate and seminal vesicles
• Scrotal skin and labia majora
• Glans penis and glans clitoris primarily
• Testes and ovaries

Q6. Which part of the anal canal drains primarily to superficial inguinal nodes?

• Anal canal above the pectinate line primarily
• Anal canal below the pectinate line
• Sigmoid colon
• Upper rectum

Q7. What fascial relationship distinguishes superficial from deep inguinal nodes?

• Superficial inguinal nodes lie superficial to the fascia lata
• Superficial nodes lie deep to the fascia lata
• Both groups lie inside the femoral canal
• Deep nodes lie only in subcutaneous tissue

Q8. Which vein pierces the cribriform fascia at the saphenous opening near the vertical node group?

• Small saphenous vein
• Popliteal vein
• Great saphenous vein
• Deep femoral vein

Q9. Why can an infected wound on the medial leg produce superficial inguinal lymphadenopathy?

• The femoral artery transports lymph from the wound
• The nodes are part of the knee capsule
• The medial leg drains through superficial lymphatics toward these nodes
• The nodes supply motor fibers to the leg

Q10. Which superficial body region outside the lower limb can contribute lymph to the horizontal inguinal group?

• Upper posterior scalp
• Forearm
• Lower anterior abdominal wall
• Upper thorax above the clavicle
