Which muscles comprise the 'toe in hamstring'?

• A. Semimembranosus and Semitendinosus
• B. Gracilis
• C. Adductor magnus
• D. Biceps femoris

Answer: (A)

The toe-in hamstring refers to the muscles that medially rotate the leg when the knee is flexed. The two muscles that form this group are the semimembranosus and semitendinosus. They sit on the inner (medial) side of the thigh, cross the knee, and work together to flex the knee while rotating the tibia inward, which brings the toes toward the midline. The other options don’t define this group: the biceps femoris is on the lateral side and promotes external rotation of the leg when the knee is flexed, while adductor magnus mainly acts as a hip adductor (with a hamstring portion mainly involved in hip extension), and gracilis is an inner-thigh adductor that is not part of the hamstring group responsible for toe-in.
