Flashcards

Great Saphenous Vein

A large vein that begins on the foot, runs up the medial side of the leg, and ends in the thigh near the groin. It is important for returning blood from the leg back to the heart.

Superficial External Pudendal Artery

A superficial artery that branches off the femoral artery and runs towards the external genital organs.

Superficial Epigastric Artery

A superficial artery that branches off the femoral artery and runs upwards towards the belly button (umbilicus).

Superficial Circumflex Iliac Artery

A superficial artery that branches off the femoral artery and runs upwards along the hip bone (iliac crest).

What is one of the main functions of the Iliotibial Tract?

The Iliotibial Tract helps to fix the condyles of the tibia below the femur, which is essential for maintaining balance during standing.

What is a common use for the Great Saphenous Vein in surgery?

The Great Saphenous Vein can be used to replace blocked arteries in the heart, acting like a detour for blood flow.

What causes varicose veins?

When the valves inside the Great Saphenous Vein stop working properly, blood pools in the vein, causing it to bulge and twist.

Study Notes

Iliofibial Tract

  • It is a thick band of fascia lata
  • It lies on the lateral aspect of the thigh
  • Attachments:
    • Above: to the tubercle of iliac crest
    • Below:
      • Lateral border of patella
      • Lateral condyle of tibia
      • Capsule of knee joint
  • Muscles attached to the tract:
    • It gives insertion to 2 muscles
      • Tensor fascia latae
      • The superficial gluteus maximus
  • Functions of iliofibial tract
    • Extends (prolongs) the insertion of gluteus maximus and tensor fascia latae downwards to reach below the knee
    • Fixes the condyles of the tibia below the condyles of the femur during prolonged standing
    • Acts as a splint for the knee joint keeping the limb in the erect position

Saphenous Opening

  • It is an oval opening in fascia lata
  • Site: its center lies 1 1/2 inches below and lateral to the pubic tubercle
  • Size: 3 x 1 1/2 cm
  • Margins: it has sharp upper, lateral and lower margins (which open from the falciform margin of the saphenous opening).
  • Overlying fascia: the opening is closed by a thin layer of perforated fascia called cribriform fascia
  • Underlying structures:
    • Femoral canal medially
    • femoral vein lies behind its lateral margin
    • femoral artery lies behind its lateral margin
  • Structures passing through it:
    • Superficial inguinal arteries
    • Great saphenous vein
    • Lymphatic vessels
