Fascia, Vessels, and Cutaneous Nerves of Lower Limb Flashcards
The subcutaneous tissue of the hip and thigh is continous with what other fascia?
The fascia of the inferior part of the anterolateral abdominal wall and buttocks
Where does the subcutaneous tissue lose its fat?
At the anterior, lateral part of the knee
Why is the deep fascia of the lower limb important?
It limits outward extension of contracting muscles, making muscular contraction more efficient in compressing the veins to push blood toward the heart
What is the deep fascia of the thigh also known as?
Fascia lata
Why is the fascia lata important?
It encloses the large thigh muscles
What does the fascia lata form?
The iliotibial tract
The iliotibial tract is the aponeurosis for which muscles?
Gluteus maximus and tensor fasciae latae
How long is the iliotibial tract?
It extends from the iliac tubercle to the anterolateral tibial tubercle on the lateral condyle of the tibia
What is formed when the crural fascia thickens?
Extensor retinacula
What are the two major superficial veins?
Great and small saphenous veins
How is the great saphenous vein formed?
Union of the dorsal digital vein and the dorsal venous arch of the foot
What does the great saphenous vein empty into?
Femoral vein
What is important about the blood flow in lower limb?
Perforating veins penetrate deep fascia and prevent blood flow from deep to superficial veins so that muscular contractions propel blood toward the heart against gravity
Where deep veins from the leg flow into?
Popliteal vein posterior to the knee which becomes the femoral vein in the thigh
What does the femoral vein become?
It passes deep to the inguinal ligament to become the external iliac vein
