The following image shows the leg muscles labeled diagram. As we see from the leg muscles labeled diagram, the thigh has three sets of strong muscles: the hamstring muscles, the quadriceps muscles, and the adductor muscles. As per the labeled diagram, the quadriceps and hamstrings work together to extend and flex the leg. In addition to this, the adductor muscles pull the legs together. The following leg muscles labeled diagram also illustrates that the mammalian leg is important: gastrocnemius muscle, gluteus muscles, quadriceps femoris, sartorius, and soleus.
