Intermediate Superior Gluteal Nerve Quiz

Q1. From which divisions of the contributing ventral rami is the superior gluteal nerve formed?

• Dorsal rami
• Anterior divisions
• White rami communicantes
• Posterior divisions

Q2. Which artery accompanies the superior gluteal nerve through the greater sciatic foramen?

• Obturator artery
• Profunda femoris artery
• Superior gluteal artery
• Inferior gluteal artery

Q3. Between which muscles does the superior gluteal nerve travel after entering the gluteal region?

• Biceps femoris and semitendinosus
• Gluteus medius and gluteus minimus
• Gluteus maximus and skin
• Adductor longus and gracilis

Q4. Which branch of the superior gluteal nerve continues toward tensor fasciae latae?

• Inferior branch
• Tibial branch
• Common fibular branch
• Superior branch

Q5. Which muscle is particularly associated with the superior branch of the superior gluteal nerve?

• Semitendinosus
• Adductor magnus
• Gluteus medius
• Gluteus maximus

Q6. Why can superior gluteal nerve injury cause pelvic instability during walking?

• It eliminates ankle plantarflexion
• It weakens the hip abductors that stabilize the pelvis
• It paralyzes quadriceps
• It denervates all hamstrings

Q7. What happens in a positive Trendelenburg sign when the patient stands on the affected limb?

• The affected knee becomes fixed in extension
• The foot becomes fixed in plantarflexion
• The pelvis drops on the weight-bearing side
• The pelvis drops on the unsupported side

Q8. How does the pelvic exit of the superior gluteal nerve differ from that of the inferior gluteal nerve?

• It exits through the lesser sciatic foramen
• It exits through the femoral ring
• It exits through the obturator canal
• It exits superior to piriformis

Q9. Why can the superior gluteal nerve be at risk during some surgical approaches to the lateral hip?

• It lies inside the femoral artery
• It remains inside the vertebral canal
• It passes behind the medial malleolus
• It runs between gluteus medius and gluteus minimus

Q10. Which action can be weakened when tensor fasciae latae loses superior gluteal nerve supply?

• Hip abduction and medial rotation
• Hip adduction and lateral rotation
• Knee flexion only
• Ankle plantarflexion and inversion
