Quizplus · Accepted Answer

An antagonist is a muscle that opposes the action of another muscle. In this case, the muscle on the posterior side of the thigh is most likely the hamstrings. The hamstrings flex the knee joint and extend the hip joint. The muscles that oppose this action are located on the anterior side of the thigh and include the quadriceps, which extend the knee joint and flex the hip joint. Therefore, the correct choice is A – the antagonist muscle would be found on the anterior side of the thigh.
