Gracilis insertion site?

Gracilis insertion site?

• A. Superior border of pubis
• B. Ischial tuberosity
• C. Medial surface of tibia
• D. Lateral condyle of femur

Answer: (C)

Gracilis inserts on the medial surface of the tibia, just below the medial condyle, as part of the pes anserinus with sartorius and semitendinosus. This placement explains its function in knee flexion and medial rotation when the knee is flexed, as well as aiding thigh adduction. The superior border of the pubis is where gracilis originates, not inserts. The ischial tuberosity is associated with other muscles (like the hamstrings), and the lateral condyle of the femur is not a gracilis insertion.
