medial & lateral head
Suprapatellar bursa

Iliopectineal bursa (not pictured)
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
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
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
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
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
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
The bone that holds it all together
Anterior landmarks
Head
Neck
Greater trochanter
Lesser trochanter
Lateral condyle
Medial condyle
Intercondylar fossa
Medial epicondyle
Lateral epicondyle
