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 proximal tibia, just below the medial condyle, where it joins the tendons of sartorius and semitendinosus to form the pes anserinus. This placement enables it to help flex the knee and adduct the thigh. The superior border of the pubis is where gracilis originates, not inserts, and the ischial tuberosity is a typical origin for the hamstrings, while the lateral condyle of the femur is not where gracilis attaches. So, the medial surface of the tibia is the correct insertion site.
