Femoral Triangle

Question 1

Boundaries of femoral triangle

Answer 1

Superior- inguinal ligament
Lateral - sartorius
Medial - adductor longus
Roof - fascia lata
Floor - iliopsoas and pectineus

Question 2

Contents of femoral triangle

Answer 2

Lateral femoral cutaneous nerve

Femoral nerve

femoral artery and vein in femoral sheath

Profunda femoris artery, which gives rise to lateral and medial femoral circumflex arteries

Question 3

Profunda femoris

Answer 3

Main supplier of blood to the thigh

Question 4

Medial and lateral femoral circumflex arteries

Answer 4

Main suppliers to the head and neck of the femur

Question 5

Venous system of the lower extremity

Answer 5

Dorsal Venus arch
Great saphenous vein
Perforating branches
Venous valves

Question 6

Venous valves

Answer 6

Cup like endothelium that fill from above

Prevent reflux of blood distally

Valve mechanism allows blood to overcome force of gravity

Question 7

Adductor canal

Answer 7

Narrow fascial tunnel in the anterior thigh, that allows passage for the memorial vessels to the popliteal fossa

Hunters canal
Subsartiorial canal

Question 8

Location of adductor canal

Answer 8

The canal begins at the point where sartorius muscle passes over the adductor longus muscle

It ends at the adductor hiatus in the tendon of the adductor Magnus muscle

Question 9

Contents of adductor canal

Answer 9

Femoral artery and vein enter the adductor canal

As femoral artery and vein exit through the adductor hiatus, they change names to the popliteal artery and vein

Saphenous nerve
Cutaneous branch of the femoral nerve

Nerve to Vastus medialis, exit the canal to innervate vastus medialis before the canal continues to the adductor hiatus

Question 10

Dorsal Venus arch drains into

Answer 10

1. Lateral marginal vein
   - past behind the lateral malleolus
   - become small, saphenous vein
   -Posteriorly drain into the popliteal vein
2. medial marginal vein
   -pass anterior to the medial malleolus
   - Travel on the medial aspect of the leg and knee
   - And become the great saphenous vein
   - drain into the femoral vein

Question 11

What travels through the femoral canal

Answer 11

Lymphatics
