The fourth is a bit different.  The rectus femoris is essentially the inverse of the hamstrings.  It inserts on the tibial tuberosity via the patella just like the rest of your quads, but it originates on the anterior inferior iliac spine of the ilium (just above the hip), meaning it can both flex the hip and extend the knee.  However, much like the hamstrings had a longer internal moment arm at the hip than the knee, making them more effective hip extensors than knee flexors, the rectus femoris has a longer internal moment arm at the knee than the hip, making it a more effective knee extensor than a hip flexor.
