Intermediate Superior Rectal Artery Quiz

Q1. At approximately which level does the inferior mesenteric artery continue as the superior rectal artery?

• Near L1 at the celiac origin
• Near T6
• Near S3
• At the femoral ring

Q2. Which named arterial junction lies between the last sigmoid artery and the superior rectal artery?

• Sudeck's point
• Griffith's point
• Calot's triangle
• McBurney's point

Q3. Which arteries usually arise from the internal iliac system and anastomose with superior rectal branches?

• Middle rectal arteries
• Middle colic arteries
• Jejunal arteries
• Short gastric arteries

Q4. Which arterial system supplies the superior rectal artery?

• Celiac arterial system
• Subclavian arterial system
• Inferior mesenteric arterial system
• External iliac arterial system

Q5. Why are rectal arterial anastomoses anatomically important?

• They form the portal vein
• They connect mesenteric and internal iliac arterial territories
• They connect the renal arteries
• They supply the spleen

Q6. Which tissue plane contains the superior rectal vascular branches around the rectum?

• Lesser sac
• Broad ligament only
• Falciform ligament
• Mesorectum

Q7. Which statement best describes the superior rectal artery near the upper rectum?

• It supplies only the abdominal wall
• It terminates in the pancreas
• It divides into descending rectal branches
• It enters the renal sinus

Q8. Which connection provides continuity between sigmoid-colon and upper-rectal arterial territories?

• Middle colic to ileocolic anastomosis
• Left gastric to right gastric anastomosis
• Renal to gonadal anastomosis
• Lowest sigmoid to superior rectal anastomosis

Q9. Which feature distinguishes the superior rectal artery from the middle rectal artery?

• It supplies the spleen
• It is always paired at its origin
• It arises from the celiac trunk
• It arises from the IMA rather than the internal iliac system

Q10. Which statement best describes the collateral supply of the rectum?

• The rectum has only one end artery
• Rectal arteries do not anastomose
• Only the celiac trunk supplies the rectum
• Superior, middle, and inferior rectal branches communicate
