The gluteal tuberosity serves as an attachment for which muscle?

• A. Adductor Magnus (Adductor/Lateral)
• B. Gluteus Medius
• C. Gluteus Maximus
• D. Tensor Fasciae Latae

Answer: (C)

The gluteal tuberosity is the proximal femur’s posterior rough patch that serves as the insertion point for the gluteus maximus. This large muscle is the main hip extensor and powerful external rotator, and its tendon anchors here (with some fibers also attaching to the iliotibial tract). That connection explains why extending the thigh and stabilizing the hip rely on the gluteal tuberosity. The other muscles attach to different sites—gluteus medius to the greater trochanter, tensor fasciae latae to the iliotibial tract and iliac crest, and the adductor magnus along the linea aspera/adductor tubercle—so their insertions aren’t on the gluteal tuberosity.
