Quizplus · Accepted Answer

The superior gemellus is one of the short external rotator muscles of the hip joint. Its main action is to laterally rotate the thigh at the hip joint, making C the correct answer. Flexion of the thigh at the hip joint is primarily done by the hip flexor muscles such as the iliopsoas. Flexion of the trunk at the spinal joints is done by core muscles such as the rectus abdominis. Lateral rotation of the leg at the knee joint is done by the popliteus muscle.
