Question

The muscles which help in the movement of legs are

• A. Biceps and triceps.
• B. Quadriceps femoris and gastrocnemius.
• C. Biceps and abductor.
• D. Quadriceps and triceps.

Answer 1

The correct option is B Quadriceps femoris and gastrocnemius.

Quadriceps femoris main function is to facilitate the extension of the knee. The gastrocnemius muscle is a muscle located on the back of the lower leg. The flexing of the muscle during walking and bending of the knee pulls on the femur, pulling it toward the tibia in the lower leg and causing the knee to bend thus helping the movement of legs.
