Insertion. — (1) The lateral part of the anterior surface of the patella; (2) the 

 tendon of the rectus femoris. 



Action. — To extend the stifle joint. 



Structure. — The fibers are directed downward and forward, many being in- 

 serted into the tendinous sheet which covers the side of the rectus. A bursa is 

 usually present between the distal end and the patella. 



Relations. — Laterally, the fascia lata and skin, tensor fasciae latae, superficial

gluteus, and biceps femoris; medially, the femur and femoro-patellar joint capsule, 

 the rectus femoris, vastus intermedins, and the iliaco-femoral artery. 



Blood-supply. — Iliaco-femoral artery. 



Nerve-supply. — Femoral nerve. 



(3) Vastus medialis.— This resembles the preceding muscle, and lies in a sim- 

 ilar position on the medial side of the femur. 



Origin. — The medial surface of the femur, from the neck to the distal third. 



Insertion. — (1) The medial border of the patella and its cartilage, and the
