- Right branch
- Superior rectal branch
- Appendicular branch
Q2. Which branch extends toward the left colic flexure?
- Cystic branch
- Ileal branch
- Left branch

Q3. What is the main significance of the left middle colic to left colic anastomosis?
- It connects the renal and gonadal arteries
- It forms the portal vein
- It connects SMA and IMA territories
- It supplies only the pancreas
Q4. Which embryologic portion of the transverse colon is classically supplied by the superior mesenteric arterial system?
- Entire descending colon
- Entire sigmoid colon
- Proximal two-thirds
- Distal one-third only
Q5. Which arterial structure provides continuity between middle colic branches and neighboring colic vessels along the colon?
- Renal arterial arcade
- Marginal artery of the colon
- Pancreaticoduodenal arcade
- Gastric arterial circle
Q6. Which region is a classic watershed between middle colic and left colic arterial territories?
- Cecal apex
- Pylorus
- Anal verge
- Left colic flexure
Q7. Which artery can provide collateral flow to the right branch of the middle colic artery?
- Superior rectal artery
- Right colic artery
- Inferior phrenic artery
- Left gastric artery
Q8. Which relationship is characteristic of the middle colic artery?
- It lies entirely in the lesser omentum
- It enters the renal hilum
- It courses within the transverse mesocolon
- It passes through the inguinal canal
Q9. Which branch pattern is typical after the middle colic artery reaches the transverse mesocolon?
- Termination as a single appendicular artery
- Bifurcation into right and left branches
- Continuation as the superior rectal artery
- Division into renal segmental arteries
Q10. Why is the middle colic artery important for transverse-colon collateral circulation?
- It supplies only the abdominal wall

- Its branches connect neighboring colic arterial territories
- It drains directly into the portal vein
