The arteria femoralis (thigh artery) is the continuation of the arteria iliaca externa, the artery supplying the leg . Just below the inguinal ligament, it gives off the roughly equally strong arteria profunda femoris , which bends downwards and provides the main supply for the thigh . In domestic animals, the deep femoral artery already emerges from the external iliac artery. The femoral artery itself remains relatively superficial and continues straight towards the lower leg .
The femoral artery passes under the inguinal ligament together with the femoral vein . They pull through the lacuna vasorum , which is bounded by the inguinal ligament ( ligamentum inguinale ), the pecten ossis pubis with the ligamentum pectineum and the arcus pectineus . The femoral nerve does not follow the course of the artery here, but passes through the lacuna musculorum with the iliopsoas muscle . It then lies first on the pectineus muscle ( iliopectinea fossa ), then on the adductor longus muscle , then on the adductor magnus muscle in the adductor canal , covered in front by the vastus medialis muscle . Through a gap in the broad tendon of the adductor magnus muscle ( hiatus adductorius ) it comes into the hollow of the knee , where it is called the popliteal artery .
In its course, the femoral artery gives off the following branches:
- Superficial epigastric artery
- Arteria circumflexa ilium superficialis
- External pudendal artery (usually several)
- Descending artery genus
- Arteria profunda femoris
In domestic mammals, the femoral artery runs from the lacuna vasorum over the thigh gap to the hollow of the knee .
It releases the following branches:
- Arteria circumflexa femoris lateralis : supplies the quadriceps
- Arteriae caudales femoris : several vessels, they supply the muscles of the posterior thigh and lower leg muscles
- Saphenous artery
- Arteria genus descendens : supplies the knee area
