What are the origins and insertions of the quadriceps group?

The rectus femoris originates at the AIIS of the pelvis, and is the only muscle of the group to cross the hip joint. The other three muscles (vastus medialis, intermedialis, and lateralis) all originate at the femur, around the intertrochanteric line. The quadriceps then insert into the tibial tuberosity, via the patellar tendon.
