FEMORAL VESSELSTracing the supply of the lower extremeties
Common Femoral Artery (CFA)Travels two-thirds of the
thighPierces the adductor
magnusReaches the popliteal fossa
behind the kneeLies on the psoas major,
pectineusBranches to the deep (DFA)
and superficial femoral artery
CFADFA
FEMORAL VESSELSTracing the supply of the lower extremities
Deep Femoral Artery (DFA)Also known as the profundaBranches from the CFA
posteriorlyTravels closer to the femur
than the SFABetween pectineus and
adductor longusBranches into perforating
branches that perforate the adductor brevis and magnus adjacent to the femur.
DFA
FEMORAL VESSELSTracing 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
FEMORAL NERVEInnervating the muscles of locomotion
Femoral NerveLargest branch of the
lumbar plexusEmerges underneath the
the inguinal ligament and branches into anterior and posterior
Lies lateral to the femoral artery in the femoral triangle
FEMORAL NERVEInnervating the muscles of locomotion
Anterior Division Include motor nerves to
the pectineus and sartoriusAlso more cutaneous
branchesNerve 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
FEMORAL NERVEInnervating 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
