The descending department of the lateral circumflex femoral artery runs down the leg and is situated behind the rectus femoris muscle.
The descending department of the lateral circumflex femoral artery provides the vastus lateralis muscle (a part of the quadriceps muscle of the thigh), with an extended department that travels by way of the muscle downward so far as the knee. It connects with the superior lateral genicular artery, which is accompanied by the vastus lateralis muscle and the department of the femoral nerve. This artery gives blood to the vastus lateralis and intermedius and likewise provides a number of perforating veins to the pores and skin, which overlies the fascia lata and lateral elements of the knee.
The department is among the foremost communication channels between the superficial and deep femoral techniques of the legs. The descending department of the lateral circumflex femoral artery could begin from the profunda artery or from the femoral artery, and varies between people—this is called anatomical variations.
