Which muscle inserts on the adductor tubercle?

• A. Adductor Longus
• B. Gracilis
• C. Adductor Magnus
• D. Pectineus

Answer: (C)

The important idea here is the specific insertion site of the thigh adductor muscles. The adductor tubercle is a small bump on the distal end of the femur on the medial side, and the tendon of the hamstring portion of the adductor magnus attaches there. This makes the adductor magnus the only one in the group that inserts at that tubercle. The other muscles insert in different places: adductor longus attaches along the linea aspera, gracilis attaches to the proximal medial tibia (pes anserinus), and pectineus attaches on the femur near the lesser trochanter. So the muscle that inserts on the adductor tubercle is the adductor magnus.
