While this muscle has a variable presentation, it consistently originates at the proximal femur, runs between the vastus lateralis and vastus intermedius muscles, and inserts distally at the medial aspect of the patellar base. In addition, cadaver studies have confirmed the presence of a sixth muscle, the tensor vastus intermedius. There is a small fifth muscle of the quadriceps complex - the articularis genus muscle - that is not often included. All four parts of the quadriceps muscle ultimately insert into the tuberosity of the tibia via the patella, where the quadriceps tendon becomes the patellar ligament. The other parts of the quadriceps arise from the surface of the femur.
The rectus femoris arises from the anterior inferior iliac spine and from the superior edge of the acetabulum. Typically, it cannot be seen without dissection of the rectus femoris. on the top or front of the thigh), but deep to the rectus femoris muscle. The vastus intermedius muscle lies between vastus lateralis and vastus medialis on the front of the femur (i.e.The vastus medialis muscle is on the medial side of the femur (i.e.The vastus lateralis muscle is on the lateral side of the femur (i.e.The rectus femoris muscle occupies the middle of the thigh, covering most of the other three quadriceps muscles.The quadriceps femoris muscle is subdivided into four separate muscles (the 'heads'), with the first superficial to the other three over the femur (from the trochanters to the condyles):
