Which muscle is the largest gluteal muscle that extends the hip?

• A. Gluteus Maximus
• B. Gluteus Medius
• C. Tensor Fasciae Latae
• D. Piriformis

Answer: (A)

Hip extension is the primary action of the gluteus maximus, and it is the most massive muscle in the gluteal region. Its fibers run from the ilium and sacrum down to the femur and the iliotibial band, giving it the power to extend the hip strongly when moving from a bent position to upright, climbing, jumping, or rising from a chair. This bulk and strong extensor function define why it’s the largest gluteal muscle. The other muscles in the group have different roles and smaller size. The gluteus medius sits on the outer hip and mainly abducts the thigh and helps stabilize the pelvis during walking. The tensor fasciae latae acts on the hip and knee through the iliotibial band and is not a primary gluteal muscle. The piriformis is a small deep rotator of the hip, not involved in major hip extension.
