- Left branch
- Appendicular branch
- Right branch
Q2. Which branch extends toward the left colic flexure?

Q3. What is the main significance of the left middle colic to left colic anastomosis?
- It supplies only the pancreas
- It connects SMA and IMA territories
- It connects the renal and gonadal arteries
- It forms the portal vein

- Entire sigmoid colon
- Entire descending colon
- Distal one-third only
- Proximal two-thirds
Q5. Which arterial structure provides continuity between middle colic branches and neighboring colic vessels along the colon?
- Gastric arterial circle
- Marginal artery of the colon
- Renal arterial arcade
- Pancreaticoduodenal arcade
Q6. Which region is a classic watershed between middle colic and left colic arterial territories?
- Cecal apex

- Left colic flexure
- Pylorus
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
- Continuation as the superior rectal artery
- Division into renal segmental arteries
- Bifurcation into right and left branches
Q10. Why is the middle colic artery important for transverse-colon collateral circulation?
