The linea aspera has attachments from all of the following muscles EXCEPT:

• A. Gluteus Maximus (Insertion)
• B. Adductor Longus (Insertion)
• C. Vastus Lateralis (Origin)
• D. Adductor Brevis (Insertion)

Answer: (A)

The line of attachment on the linea aspera is a key site for several thigh muscles, especially the adductors and part of the quadriceps. The vastus lateralis originates from the lateral lip of the linea aspera, while the adductor longus and the adductor brevis attach (insertion or proximal attachment) to the linea aspera. Gluteus maximus, however, does not attach there; its insertion is on the gluteal tuberosity of the femur and via the iliotibial tract. So the muscle that does not attach to the linea aspera is gluteus maximus.
