Which muscle is at the back of the thigh?

• A. Hamstring
• B. Gastrocnemius
• C. Trapezius
• D. Latissimus dorsi

Answer: (A)

The back of the thigh is where the hamstrings are. This group of three muscles—biceps femoris, semitendinosus, and semimembranosus—runs from the pelvis to the knee and mainly works to bend the knee and extend the hip, which is important in actions like running and jumping. The other muscles listed sit in different areas: the gastrocnemius is the calf muscle at the back of the lower leg, the trapezius runs across the upper back and neck, and the latissimus dorsi is a broad muscle on the lower back involved in pulling movements. So the muscle at the back of the thigh is the hamstrings.
