Lecture 7 - Femoral triangle

Question 1

5 borders of the femoral triangle

Answer 1

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

Question 2

Where does inguinal ligament attach to

Answer 2

ASIS to the pubic tubercle

Question 3

Contents of the femoral triangle

Answer 3

Femoral nerve
Femoral artery
Femoral vein - the great saphenous vein drains into the femoral vein withing the triangle
Empty space - allows the vein to distend
Lymphatics - within the femoral canal

Question 4

Femoral sheath

Answer 4

Encloses the femoral artery, vein and femoral canal containing lymph nodes

NOT the femoral nerve

Question 5

Femoral canal borders

Answer 5

Smallest and most medial aspect of teh femoral sheath

Medial - lacunar ligament
Lateral - femoral vein
Anterior - Ingluinal ligament
Posterior - Pectineal ligament

Opening - femoral ring

Question 6

How is the femoral ring closed

Answer 6

By a layer of connective tissue called the femoral septum

Pierced by the lymphatics

Question 7

What does the femoral canal consist of?

Answer 7

Lymphatic vessels - draining the deep inguinal lymph nodes

Deep lymph node- Lacunar node

Empty space - allows distention of the femoral vein and lymph nodes

Loose connective tissue

Question 8

Adductor canal borders

Answer 8

From the apex of the femoral triangle to the adductor hiatus of the adductor magnus

Anterior - sartorius
Lateral - Vastus medialis
Posterior - Adductor longus and adductor magnus

Apex of adductor canal - adductor hiatus

Question 9

Contents of the adductor canal

Answer 9

Femoral artery and vein
Femoral nerve and the saphenous nerve

As the femoral artery and vein pass through the adductor canal via the adductor hiatus into the popliteal fossa they become the popliteal artery and vein
