Intermediate Inferior Gluteal Artery Quiz

Q1. Which landmark separates the usual exit routes of the superior and inferior gluteal arteries?

• Obturator internus tendon
• Sacrotuberous ligament
• Piriformis muscle
• Inguinal ligament

Q2. Which major nerve commonly leaves the pelvis in the same infrapiriform region as the inferior gluteal artery?

• Femoral nerve
• Sciatic nerve
• Phrenic nerve
• Median nerve

Q3. Which artery can anastomose with the inferior gluteal artery in the gluteal region?

• Radial and ulnar arteries
• Anterior and posterior cerebral arteries
• Superior gluteal and profunda femoris branches
• Coronary and pulmonary arteries

Q4. Which thigh artery contributes vessels that communicate with the inferior gluteal artery?

• Internal thoracic artery
• Inferior mesenteric artery
• Profunda femoris artery
• Anterior tibial artery only

Q5. Which muscle may receive branches from the inferior gluteal artery in addition to gluteus maximus?

• Intrinsic hand muscles
• Extraocular muscles only
• Muscles of facial expression
• Deep gluteal and proximal posterior thigh muscles

Q6. What is the relationship of the inferior gluteal artery to the sacral plexus inside the pelvis?

• It passes through the brachial plexus
• It courses near branches of the sacral plexus
• It lies within the cervical plexus
• It has no relation to pelvic nerves

Q7. Which internal iliac branch may share a common origin with the inferior gluteal artery?

• Internal pudendal artery
• Inferior epigastric artery
• Renal artery
• Superior mesenteric artery

Q8. How does the usual course of the inferior gluteal artery differ from that of the internal pudendal artery after leaving the pelvis?

• Both arteries terminate inside the urinary bladder
• The internal pudendal artery enters the femoral canal
• The inferior gluteal artery enters the abdomen through the obturator canal
• The internal pudendal artery reenters through the lesser sciatic foramen

Q9. Why are gluteal arterial anastomoses important?

• They produce synovial fluid
• They connect internal iliac and femoral arterial territories
• They connect the carotid arteries to the aorta
• They drain venous blood from the pelvis

Q10. Which statement correctly compares the superior and inferior gluteal arteries?

• Both remain entirely within the pelvis
• Both normally arise from the external iliac artery
• They usually arise from different internal iliac divisions and pass on opposite sides of piriformis
• Both pass through the obturator canal
