Intermediate Gluteus Medius Quiz

Q1. Between which gluteal lines does much of gluteus medius arise from the ilium?

• Between the anterior and posterior gluteal lines
• Below the inferior gluteal line only
• Between the anterior and inferior gluteal lines
• Within the iliac fossa

Q2. Which additional superior attachment contributes to the origin of gluteus medius?

• Ischial spine
• Pecten pubis
• Pubic tubercle
• Outer lip of the iliac crest

Q3. What action is especially associated with the anterior fibers of gluteus medius?

• External rotation only
• Knee flexion
• Ankle inversion
• Internal rotation of the hip

Q4. What action can the posterior fibers of gluteus medius assist?

• Knee extension
• Internal rotation only
• Toe flexion
• External rotation of the hip

Q5. Which spinal nerve roots contribute mainly to the superior gluteal nerve supplying gluteus medius?

• L1 and L2 only
• L2, L3, and L4
• S2, S3, and S4
• L4, L5, and S1

Q6. Which artery is the principal named arterial supply associated with gluteus medius?

• Superior gluteal artery
• Obturator artery only
• Inferior epigastric artery
• Anterior tibial artery

Q7. Where do the superior gluteal nerve and vessels travel in relation to gluteus medius and minimus?

• Inside the femoral canal
• Within the adductor canal
• Between gluteus medius and gluteus minimus
• Superficial to gluteus maximus

Q8. Which bony surface receives the tendon of gluteus medius?

• Anterior surface of the patella
• Posterior surface of the tibial condyle
• Lateral surface of the greater trochanter
• Medial surface of the lesser trochanter

Q9. What happens to the pelvis when the right gluteus medius is weak and the person stands on the right leg?

• Both knees lock in flexion
• The left ankle plantarflexes automatically
• The left side of the pelvis drops
• The right side of the pelvis necessarily drops

Q10. Why is gluteus medius often described as a key frontal-plane stabilizer of the hip?

• It forms the hip joint capsule
• It counters the pelvic moment created by body weight
• It directly stabilizes the ankle mortise
• It prevents all rotation at the knee
