Anterior and medial aspects of the thigh Flashcards
Deep fascia of thigh
Fascia lata
What does the Iliotibial tract attach to?
Laterally thickens
Superiorly attaches to iliac crest
Inferior attaches to Lateral condyle of tibia
Thickening of fasica lata
Iliotibial tract
What 2 muscles do the Iliotibial tract intervene?
Right: Tensor fasciae latae muscle
Left: Gluteus maximus muscle
At the upper medial aspect of the thigh opening of fascia lata?
Saphenous opening
Why is the Saphenous opening present?
The great Saphenous vein( superficial) drains into the femoral vein(deeper vein).
Blue: femoral vein
White: Fossa ovalis
Yellow: Falciform margin
Green: Great saphenous vein
Great saphenous vein
Clinical imp of great saphenous vein
Reflected and used as coronary bypass surgery
Clinical imp of great saphenous vein
Reflected and used as coronary bypass surgery
Begining and end of great saphenous vein
Begin: Dorsum of the foot (drains venous blood from the dorsum of foot)
Runs anterior to medial malleolus
Accompanies a sensory nerve called saphenous nerve.
Ascends on the medial aspect of the thigh.
Passes through the saphenous opening Drains into femoral vein.
Sensory nerve accompanying great saphenous vein
Saphenous nerve
Small saphenous vein
Beginning and end of Small saphenous vein
Begin: dorsum of the foot
runs posterior to lateral malleolus
ascends on posterior aspect of the leg
Accompanies sural nerve( cutaneous nerve)–branch of tibial nerve.
Pierces the popliteal fossa (resemble cubital fossa)
Drains into the popliteal vein.
Right: Superficial vein
Middle: Perforating vein
Left: Deep vein
Examples of superficial vein
Great saphenous vein, small saphenous vein, cephalic vein, basilic vein
Examples of deep vein
Upper extremity: Brachial vein. Axillary vein
Lower extremity: Femoral vein
Connection of the deep and superficial vein.
Perforating vein (contain valves)
What does the perforating vein contain?
All veins contain one-way valves.
Allows blood to flow toward the heart and prevents blood from flowing in the retrograde direction.
Unfunctining of the perforating vein
Varicoses (dilatation of vein)
Superficial vein or deep vein

Tuberosity of tibia
Vastus lateralis nerve
Femoral nerve
Vastus medialis origin
Intertrochanteric line, medial lip of the asperal line
Vastus medialis insertion
Tuberosity of tibia, some fibers join the capsule of the knee joint and strengthen the knee joint
