The quadriceps are located at the anteriâ¦or thigh. It is a muscle  that reacts with hamstrings and gastrocnemius. The four muscles in  this group are the rectus femoris, vastus medius, vatus lateralis,  and the vastus intermedius.
The quadriceps as a whole has one main function, and that is to extend the lower leg. However, the rectus femoris also has another function, which is hip flexion. This is because this part of the quadriceps originates at the hip bone, unlike the other quadriceps muscles, which originate at the thigh bone.
