Practice questions on Gluteus Maximus
Gluteus maximus
- Forms the gluteal fold
- Has four bursae beneath it
- Has blood supply solely from the inferior gluteal artery
- Is the chief control of hip flexion
- Has 50% of fibres inserting into the gluteal tuberosity
Answer: D. Gluteus maximus is the chief EXTENSOR (not flexor) of the hip, particularly important when rising from sitting, climbing stairs, and running. It receives blood from both superior and inferior gluteal arteries, and the majority of its fibers insert into the iliotibial tract rather than the gluteal tuberosity. ---
Gluteus maximus:
- Is the largest muscle of the body.
- Is primarily responsible for hip extension.
- Is innervated by the inferior gluteal nerve.
- All of the above.
Answer: D. Gluteus maximus is the largest muscle in the body and plays a crucial role in hip extension, particularly when rising from a seated position or climbing stairs. It is innervated by the inferior gluteal nerve.
Gluteus maximus:

- Is innervated by the inferior gluteal nerve.
- All of the above.
Answer: D. Gluteus maximus is the largest muscle in the body and plays a crucial role in hip extension, particularly when rising from a seated position or climbing stairs. It is innervated by the inferior gluteal nerve.
Gluteus maximus:
- Is primarily responsible for hip abduction
- Is innervated by the obturator nerve
- Its superior fibers are innervated by the superior gluteal nerve
- Is a weak extensor of the hip
Answer: C. The gluteus maximus is the largest of the gluteal muscles and is a powerful hip extensor. While its superior fibers receive innervation from the superior gluteal nerve, the main motor innervation is from the inferior gluteal nerve. Hip abduction is primarily the function of the gluteus medius and minimus.
Gluteus maximus:
- Is the largest gluteal muscle.
- Is a powerful extensor of the hip.
- Is innervated by the inferior gluteal nerve.
- All of the above.
Answer: D. Gluteus maximus is the largest gluteal muscle, plays a major role in hip extension, and is innervated by the inferior gluteal nerve.
The gluteus maximus muscle is primarily responsible for which action at the hip joint?
- Adduction and medial rotation
- Flexion and abduction
- Extension and lateral rotation
- Abduction and medial rotation
Answer: C. The gluteus maximus is the strongest muscle of the hip, primarily responsible for extension and powerful lateral rotation of the hip joint. It is crucial for standing up from a seated position and climbing stairs.
