Which muscle group is located at the front of the thigh?

• A. Hamstrings
• B. Gluteals
• C. Calf
• D. Quadriceps

Answer: (D)

The muscle group at the front of the thigh is the quadriceps. They run along the front of the thigh and are the main knee extensors, meaning they straighten the knee when you push off or stand up from a chair. The rectus femoris also crosses the hip, contributing to hip flexion. The other muscle groups are located elsewhere: the hamstrings are on the back of the thigh and bend the knee; the gluteals are in the buttocks and help with hip movements; the calf muscles are in the lower leg and help with pointing the toes. So, for the front-of-thigh location, the quadriceps is the best answer.
