Which muscle forms the roof of the adductor canal (subsartorial canal)?

• A Vastus medialis
• B Gracilis
• C Adductor magnus
• D Sartorius ✓

Explanation

The adductor canal extends from the apex of the femoral triangle to the adductor hiatus. Its roof is the sartorius muscle, the lateral wall is vastus medialis, and the posterior wall is formed by adductor longus proximally and adductor magnus distally. Gracilis is a medial thigh muscle unrelated to the canal wall, making it a plausible but incorrect distractor.
