Intermediate Gluteus Maximus Quiz

Q1. Relative to the posterior gluteal line, where does the iliac origin of gluteus maximus lie?

• Between the anterior and inferior gluteal lines
• Anterior to the anterior gluteal line
• Posterior to the posterior gluteal line
• Within the iliac fossa

Q2. Which fascial attachment contributes to the broad origin of gluteus maximus?

• Plantar aponeurosis
• Cribriform fascia alone
• Thoracolumbar and gluteal fascia
• Flexor retinaculum of the ankle

Q3. How do the superior and inferior fibers of gluteus maximus differ in their accessory frontal-plane actions?

• Superior fibers assist abduction, while inferior fibers assist adduction
• All fibers act only as adductors
• Superior fibers only adduct, while inferior fibers only flex
• All fibers act only as abductors

Q4. Which arterial pair contributes importantly to the vascular supply of gluteus maximus?

• Anterior tibial and fibular arteries
• Radial and ulnar arteries
• Superior and inferior gluteal arteries
• Medial and lateral plantar arteries

Q5. Which spinal nerve roots contribute to the inferior gluteal nerve?

• L2, L3, and L4
• L1, L2, and L3
• S3, S4, and S5
• L5, S1, and S2

Q6. What is the anatomical relationship between the sciatic nerve and gluteus maximus?

• The sciatic nerve provides its motor supply
• The sciatic nerve lies entirely superficial to the muscle
• The sciatic nerve pierces the muscle belly
• The sciatic nerve lies deep to gluteus maximus

Q7. Which bursa helps reduce friction where gluteus maximus and the iliotibial tract pass over the greater trochanter?

• Trochanteric bursa
• Deep infrapatellar bursa
• Subacromial bursa
• Prepatellar bursa

Q8. Which bursa may lie between gluteus maximus and the ischial tuberosity?

• Subcutaneous olecranon bursa
• Ischial bursa
• Retrocalcaneal bursa
• Suprapatellar bursa

Q9. How can gluteus maximus influence the knee without crossing it as a fleshy muscle belly?

• Through the anterior cruciate ligament
• Through direct insertion into the patella
• Through direct insertion into the medial meniscus
• Through tension transmitted into the iliotibial tract

Q10. Why is gluteus maximus more active during stair climbing than during relaxed level walking?

• Climbing requires powerful hip extension against resistance
• Level walking completely inhibits the muscle
• The muscle acts only on the knee during climbing
• Climbing requires no hip extension
