Question: are quads and thighs the same thing?
Answer: The thigh includes the quadriceps femoris, or quads, but the quads alone are not the entire thigh. The thigh is composed of three large groups of muscles and a few much smaller muscles. The quads are a group of four muscles of the front thigh—the rectus femoris, vastus lateralis, vastus medialis and vastus intermedius.
