Advanced Greater Curvature of the Stomach Quiz

Q1. Why can the gastro-omental arterial arcade provide collateral circulation along the greater curvature?

• It connects the inferior mesenteric artery directly to the renal artery
• It has no arterial communication
• It is formed by portal venous tributaries
• It connects gastroduodenal and splenic arterial territories through an anastomosis

Q2. Which two branches of the celiac arterial system ultimately give rise to the gastro-omental vessels?

• Superior rectal and internal iliac arteries
• Renal and gonadal arteries
• Splenic artery and common hepatic artery pathways
• Left gastric and inferior mesenteric arteries

Q3. How does differential growth of the embryonic stomach produce the greater curvature?

• More rapid growth of the ventral wall creates it
• Midgut rotation creates it without gastric growth
• More rapid growth of the dorsal wall creates the long convex border
• Fusion with the transverse colon creates it

Q4. How is the greater omentum developmentally related to the greater curvature?

• It develops from the sigmoid mesocolon
• It develops from elongated dorsal mesogastrium attached to the greater curvature
• It develops from the mesentery of the appendix
• It develops from the ventral mesogastrium attached to the lesser curvature

Q5. Why is division of the gastrocolic ligament used to gain surgical access to the lesser sac?

• It enters the urinary bladder
• Opening it creates an approach into the lesser sac behind the stomach
• It exposes the spinal canal
• It opens the pleural cavity

Q6. Which venous drainage pattern best reflects the arterial arrangement along the greater curvature?

• Both drain directly into the inferior vena cava
• Both drain into the internal iliac vein
• Right drainage enters the azygos vein and left drainage enters the femoral vein
• Right drainage reaches the superior mesenteric vein and left drainage reaches the splenic vein

Q7. Why can lymphatic drainage from the greater curvature follow more than one regional pathway?

• The greater curvature has no lymphatics
• All lymph drains only to inferior mesenteric nodes
• Different vascular territories direct lymph toward different regional nodes before celiac drainage
• All lymph drains only to superficial inguinal nodes

Q8. Which anatomical relationship places the upper greater curvature near the spleen?

• The mesoappendix attaches it to the spleen
• The falciform ligament attaches it to the spleen
• The hepatoduodenal ligament connects it to the spleen
• The gastrosplenic ligament connects the upper greater curvature with the spleen

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

• The dorsal border is repositioned mainly leftward and inferiorly as the stomach rotates
• The greater curvature migrates into the pelvis
• The ventral border becomes the greater curvature without rotation
• The dorsal border becomes the lesser curvature

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

• It is a hindgut structure without peritoneal attachments
• It is a retroperitoneal border supplied by the inferior mesenteric artery
• It is a dorsal-derived convex gastric border with omental attachments, gastro-omental and short gastric vessels, portal drainage, and regional lymphatic pathways
• It is a ventral-derived concave border attached only to the lesser omentum
