Intermediate Superior Mesenteric Nodes Quiz

Q1. Why do midgut lymphatics converge toward superior mesenteric nodes?

• Midgut lymphatics broadly follow branches of the superior mesenteric artery
• Midgut lymph first enters the urinary bladder
• All lymphatics run inside arteries
• The superior mesenteric nodes are thoracic nodes

Q2. Which sequence best represents lymphatic drainage from the jejunum?

• Lacteals to superficial inguinal nodes to celiac nodes
• Lacteals directly to the portal vein
• Lacteals to axillary nodes to superior mesenteric nodes
• Lacteals to mesenteric nodes to superior mesenteric nodes

Q3. Which regional nodal group commonly relays lymph from the cecum and terminal ileum?

• Deep cervical nodes
• Ileocolic nodes
• Pancreaticosplenic nodes
• Inferior mesenteric nodes

Q4. Which regional vascular pathway commonly guides lymph from the ascending colon?

• Left gastric and splenic vessels
• Sigmoid vessels only
• Inferior rectal vessels only
• Ileocolic and right colic vessels

Q5. Which regional vascular pathway commonly guides lymph from the proximal transverse colon?

• Superior rectal vessels
• Middle colic vessels
• Left colic vessels only
• Inferior epigastric vessels

Q6. How are superior mesenteric nodes related to the abdominal aorta?

• They lie only below the inguinal ligament
• They lie anterior to the aorta near the superior mesenteric artery origin
• They lie inside the aortic lumen
• They are confined behind the sacrum

Q7. Which structure is least likely to drain primarily to superior mesenteric nodes?

• Ascending colon
• Cecum
• Jejunum
• Sigmoid colon

Q8. Why are superior mesenteric nodes involved in transport of absorbed dietary fat?

• They manufacture bile
• They drain chyle into the urinary bladder
• They lie along the route of chyle from small-intestinal lacteals
• They convert lymph into arterial blood

Q9. What is the relationship between regional midgut nodes and superior mesenteric nodes?

• They have no afferent lymphatics
• Regional midgut nodes relay lymph centrally to superior mesenteric nodes
• Regional midgut nodes drain only to axillary nodes
• Superior mesenteric nodes drain outward to skin first

Q10. Which sequence correctly traces midgut lymph toward the thoracic duct pathway?

• Regional nodes, superior mesenteric nodes, intestinal trunk, central lymphatic pathway
• Regional nodes, axillary nodes, jugular trunk, thoracic duct
• Regional nodes, popliteal nodes, subclavian trunk, thoracic duct
• Regional nodes, portal vein, liver, thoracic duct
