The vastus intermedius muscles are located in the upper anterior (anterior = 'front') of the legs of the human body.
The two vastus intermedius muscles, one of which is located in each leg, are one of the four quadriceps muscles in each upper-leg. The vastus intermedius muscles are positioned deep within the thigh, underneath the rectus femoris muscles.
