Exam 4

Question 0

Femoral triangle contents

Answer 0

Lateral to medial

1. Femoral nerve and its terminal branches
2. Femoral artery and several of its branches
3. Femoral vein and its proximal tributaries (great sapheous vein and profunda femoris vein)
4. Femoral canal
5. Deep inguinal lymph nodes and associated lymphathic vessels

Question 1

Femoral triangle

Answer 1

Superiorly: inguinal ligament–>base
Medially: adductor longus
Laterally: sartorius–>apex where the medial border of sartorius crosses the lateral border of the adductor longus
Floor: iliopsoas laterally and pectineus medially
Roof: fascia lata, cribiform fascia, subcutaneous tissue, skin

Question 2

Adductor canal

Answer 2

extends from the apex of the femoral triangle to the adductor hiatus in the tendon of adductor magnus, provides an intermuscular passage for the femoral artery and vein, the saphenous nerve, and the nerve to vastus medialis, delivering the femoral vessels to the popliteal fossa where they become popliteal vessels

Question 3

Popliteal fossa bounded by

Answer 3

Biceps femoris superolaterally,
semimembranous superomedially,
lateral and medial heads of gastrocnemius, inferolaterally/inferomedially,
skin and popliteal fascia posteriorly (roof),
popliteal surface of the femur, posterior capsule of the knee joint and the popliteus muscle (floor)

Question 4

Contents of the popliteal fossa

Answer 4

termination of the small saphenous vein,
popliteal artery and vein and their branches and tributaries,
tibial and common fibular nerves,
posterior cutaneous nerve of the thigh,
popliteal lymph nodes and lympathic vessels,
fat

Question 5

Popliteal fascia is continuous with

Answer 5

fasia lata superiorly and deep (crural) fascia of the leg inferiorly

Question 6

Popliteal artery is a continuation of the

Answer 6

femoral artery beginning where the femoral artery passes through the adductor hiatus–>passes through the popliteal fossa and ends at the inferior border of the popliteus and divides into anterior and posterior tibial arteries

Question 7

Sciatic nerve ends at

Answer 7

superior angle of popliteal fossa and divides into tibial and common fibular nerves

Question 8

Boundaries of the adductor canal

Answer 8

anteriorly and laterallu: vastus medialis

posteriorly: adductor longus and adductor magnus
medially: sartorius which overlies the groove between the above muscles, forming the roof of the canal

Question 9

Pea anserinus

Answer 9

Insertion of sartorius, gracilis and semitendinous
