Question: is vastus intermedius and rectus femoris?
Answer: Rectus femoris occupies the middle of the thigh, covering most of the other three quadriceps muscles. It originates on the ilium. ... Vastus intermedius lies between vastus lateralis and vastus medialis on the front of the femur (i.e. on the top or front of the thigh), but deep to the rectus femoris.
