Iliopectineal bursa (not pictured)

7. Femoral vessels Common Femoral Artery (CFA)
Tracing the supply of the lower extremeties
Common Femoral Artery (CFA)
Travels two-thirds of the thigh
Pierces the adductor magnus
Reaches the popliteal fossa behind the knee
Lies on the psoas major, pectineus
Branches to the deep (DFA) and superficial femoral artery
CFA
DFA

8. Femoral vessels Deep Femoral Artery (DFA) Also known as the profunda
Tracing the supply of the lower extremities
Deep Femoral Artery (DFA)
Also known as the profunda
Branches from the CFA posteriorly
Travels closer to the femur than the SFA
Between pectineus and adductor longus
Branches into perforating branches that perforate the adductor brevis and magnus adjacent to the femur.
DFA

9. Femoral vessels Superficial Femoral Artery (SFA)
Tracing the supply of the lower extremities
Superficial Femoral Artery (SFA)
Continues distally through the adductor canal
Can be found by cutting the sartorius near its middle and reflecting its two parts.
Leaves the thigh through the adductor hiatus to become the popliteal artery in the popliteal fossa
SFA

10. Femoral nerve Femoral Nerve Largest branch of the lumbar plexus
Innervating the muscles of locomotion
Femoral Nerve
Largest branch of the lumbar plexus
Emerges underneath the the inguinal ligament and branches into anterior and posterior
Lies lateral to the femoral artery in the femoral triangle

11. Femoral nerve Anterior Division
Innervating the muscles of locomotion
Anterior Division
Include motor nerves to the pectineus and sartorius
Also more cutaneous branches
Nerve to the pectineus can be found by pushing the femoral vessels medially and probing behind them for a slender branch on the medial side of the nerve

12. Femoral nerve Innervating the muscles of locomotion Posterior Division
Include the saphenous nerve
Long sensory nerve to the medial knee
Also includes the four motor branches to the quadriceps femoris heads
Rectus femoris enters on the superior deep surface of the muscle
Vastus lateralis enters on the lower part of that muscle with the lateral circumflex femoral artery
Vastus medialis branch travels with the saphenous nerve and enters the muscle at about its middle
The vastus intermedius branches enter the anterior surface of the muscle about the midpoint of the thigh
