Anterior Aspect Of Thigh

Front 1

The Great Saphenous Vein

Back 1

-begins at medial end of dorsal venous arch of the foot
-passes anterior to the medial malleolus, runs on medial side of lower limb
-passes thru saphenous opening (fossa ovalis)
-empties into the femoral vein
-commonly used for coronary bypass surgery

Front 2

The Small Saphenous Vein

Back 2

-begins at lateral end of dorsal venous arch
-passes along lateral side of foot with sural nerve, behind lateral malleolus
-ascends with sural nerve and terminates in the popliteal vein

Front 3

Femoral Vein

Back 3

-follows the femoral artery as a continuation of the popliteal vein
-medial to femoral artery
-lies immediately medial to the femoral artery

Front 4

Popliteal vein

Back 4

ascends through the popliteal fossa
-receives the small saphenous vein

Front 5

contents of the femoral triangle

at the apex of the femoral triangle, a stab or bullet may penetrate all 4 vessels of the thigh

Back 5

-femoral vein, artery and nerve (and their respective branches)
-deep inguinal lymph nodes
-profunda femoris artery and vein and their circumflex branches

Front 6

Profunda femoris (deep femoral) artery

Back 6

-begins below the inguinal ligament
-is a branch of the femoral artery and supplies many muscles of the thigh
-medial femoral circumflex branch: leaves the triangle thru pectineus and iliopsoas
-lateral femoral circumflex branch passes laterally thru or posterior to the branches of the femoral nerve, disappears below the sartorius and rectus femoris muscle and terminates in 3 (ascending, transverse, and descending) branches

Front 7

Femoral Artery

Back 7

-continuation of external iliac artery
-vulnerable to injury because of its relatively superficial position in the femoral triangle

Front 8

Branches of the Femoral Artery

Back 8

1. Superficial epigastric
2. superficial circumflex iliac
3. superficial external pudendal
4. deep external pudendal
5. profunda femoris
6. medial femoral circumflex
7. lateral femoral circumflex
8. descending genicular artery

Front 9

medial femoral circumflex artery

Back 9

-supplies most of the blood to the neck and head of the femur (except for a small proximal part that receives blood from a branch of the obturator artery)
