Advanced Lesser Curvature of the Stomach Quiz

Q1. Why can the right and left gastric arteries provide collateral blood flow along the lesser curvature?

• They do not communicate
• They are branches of the inferior mesenteric artery
• They drain directly into the inferior vena cava
• They form an anastomotic channel along the lesser curvature

Q2. Which developmental relationship explains the attachment of the lesser omentum to the lesser curvature?

• The mesentery of the ileum becomes the lesser omentum
• The ventral mesogastrium persists as the lesser omentum along the ventral-derived lesser curvature
• The transverse mesocolon becomes the lesser omentum
• The dorsal mesogastrium becomes the lesser omentum

Q3. How does differential growth of the embryonic stomach create the lesser curvature?

• Slower growth of the ventral wall creates the shorter concave border
• Midgut rotation alone creates it
• Fusion with the liver creates the curvature
• Faster growth of the ventral wall creates the greater curvature

Q4. Why is the left gastric vein clinically important near the proximal lesser curvature?

• It is the main systemic vein of the lower limb
• It participates in a portal-systemic connection with esophageal veins
• It supplies arterial blood to the stomach
• It drains directly to the inferior vena cava without portal connections

Q5. Which statement best describes vagal relationships along the lesser curvature?

• The phrenic nerves form the gastric plexus
• Gastric vagal branches course along the lesser curvature as anterior and posterior nerves of Latarjet
• Only sympathetic fibers reach the lesser curvature
• The pudendal nerves run along the lesser curvature

Q6. Why is preservation of terminal vagal branches near the lesser curvature relevant in highly selective vagotomy?

• Selective division can reduce vagal input to acid-secreting stomach while preserving distal gastric motor branches
• It divides the phrenic nerve to relax the diaphragm
• It interrupts the inferior mesenteric artery
• It removes all sympathetic innervation to the colon

Q7. How does lymph from the lesser curvature generally reach the celiac nodal group?

• Through axillary nodes to cervical nodes
• Through gastric nodes along gastric vessels toward celiac nodes
• Through popliteal nodes to inguinal nodes
• Only through inferior mesenteric nodes

Q8. Which arterial territories are linked by the gastric arterial anastomosis along the lesser curvature?

• Renal and gonadal territories
• Internal and external iliac territories
• Superior and inferior mesenteric territories
• Left gastric and hepatic arterial pathways of the celiac system

Q9. How does stomach rotation affect the lesser curvature during development?

• The ventral border is repositioned mainly rightward and superiorly as the stomach develops
• The ventral border becomes the greater curvature on the left
• The dorsal border becomes the lesser curvature without rotation
• The lesser curvature migrates into the pelvis

Q10. Which statement best integrates the anatomy of the lesser curvature?

• It is a ventral-derived concave gastric border with lesser omental attachment, gastric vascular anastomoses, lymphatics, vagal branches, and the angular incisure
• It is a hindgut structure without autonomic or peritoneal relationships
• It is a dorsal-derived convex border attached to the greater omentum
• It is a retroperitoneal midgut border supplied by the inferior mesenteric artery
