The original version of this image had the vastus intermedius labeled as the rectus femoris. As the rectus is a superficial muscle of the thigh (and does not dive deep between the vastus lateralis and medialis muscles as suggested by the original artwork), that original label was incorrect (and has now been fixed). This illustration shows the vastus intermedius after the rectus femoris has been dissected away.

Thats fine, however what we see is neither vastus intermedius nor rectus. Perhaps it 'wanted' to become rectus, but then it "dived deep between" the vastus lateralis and medialis. Wonder, whatever it is doing there ;-) -- 17:26, 28 September 2007 (UTC)

The disputed muscle in this photo appears to have the origin of rectus femoris and the insertion of vastus intermedius. Vastus intermedius would start inferior to the muscle shown here. Rectus femoris is the only portion of the quadriceps with any origin on the pelvis.

That image is wrong, the muscle labeled as the vastus intermedius muscle is the rectus femoris muscle. Take a look to Nether Atlas or any other anatomy atlas.
