Intermediate Right Colic Artery Quiz

Q1. Which branch of the right colic artery generally extends toward the hepatic flexure?

• Sigmoid branch
• Ascending branch
• Appendicular branch
• Descending branch

Q2. Which branch generally extends toward the lower ascending colon?

• Left gastric branch
• Descending branch
• Superior rectal branch
• Ascending branch

Q3. Which arterial connection links the right colic territory with the transverse-colon circulation?

• Right colic to renal anastomosis
• Right colic to left gastric anastomosis
• Right colic to middle colic anastomosis
• Right colic to superior rectal anastomosis

Q4. Which arterial connection links the right colic territory with the ileocecal arterial network?

• Right colic to ileocolic anastomosis
• Right colic to left gastric anastomosis
• Right colic to inferior rectal anastomosis
• Right colic to splenic anastomosis

Q5. Which feature of the right colic artery is particularly variable?

• Its function as a vein
• Its origin from the mesenteric arterial tree
• Its passage through the inguinal canal
• Its entry into the renal hilum

Q6. Why does the right colic artery contribute to collateral circulation of the ascending colon?

• It connects middle colic and ileocolic territories
• It connects renal and gonadal arteries
• It is an end artery without anastomoses
• It drains into the portal vein

Q7. Which artery supplies the ascending colon if a distinct right colic artery is absent?

• Ileocolic and middle colic arteries
• Left gastric and splenic arteries
• Renal and gonadal arteries
• Superior and inferior rectal arteries

Q8. What is the relationship of right colic branches to the marginal artery?

• They terminate only in the pancreas
• They contribute to the marginal arterial network
• They form the portal vein
• They bypass the colon entirely

Q9. Which embryologic fact explains the usual SMA-based supply of the ascending colon?

• The ascending colon is foregut-derived
• The ascending colon is midgut-derived
• The ascending colon is hindgut-derived
• The ascending colon develops from the cloaca only

Q10. Which statement best describes the usual right colic arterial distribution?

• It terminates in the spleen
• It supplies only the rectum
• It supplies the stomach along the lesser curvature
• It supplies the ascending colon and joins adjacent colic vessels
