Sample Practice Questions (Active Recall)

Showing 3 of 130+

Q1.Which of the following best explains why the gluteus maximus is recruited primarily during forceful activities such as running or climbing rather than during quiet standing?

AIts blood supply from the inferior gluteal artery is restricted during low-intensity activities
BIt is innervated by the superior gluteal nerve, which has a higher activation threshold
CIt crosses only the hip joint and cannot assist with knee stabilization
DIt functions as a powerful extensor of the thigh that is only engaged when substantial force is required

Q2.What is the consequence of superior gluteal nerve palsy on pelvic stability during single-leg stance?

AThe pelvis drops on the unsupported side, producing a positive Trendelenburg sign
BThe pelvis elevates on the unsupported side due to overactive hip abductors
CThe hip joint dislocates posteriorly due to loss of deep lateral rotator function
DThe femur medially rotates excessively, causing internal rotation deformity

Q3.How does the piriformis muscle serve as a critical anatomical landmark in the gluteal region?

AIt forms the lateral boundary of the femoral triangle
BIt marks the insertion point of the sciatic nerve onto the femur
CIt separates the superficial and deep gluteal muscle groups
DIt divides the gluteal region into superior and inferior parts, determining the exit points of neurovascular structures
