Femoral Artery

A. femoralis is a continuing artery a. iliaca externa from lig. inguinale. ''AND. femoralis'' passes through the lacuna vasorum, where it is located centrally next to the nervus femoralis, which lies most laterally and runs through the lacuna musculorum. ''AND. femoralis then runs into the popliteal fossa through the hiatus adductorius''. V. femoralis, on the other hand, is located more medially and gradually passes behind the artery until it reaches the outer side.

According to the course, a. femoralis has three sections: A sensitive branch from the femoral nerve - the saphenous nerve accompanies the artery to the last two sections.
 * 1) Part in trigonum femorale and fossa iliopectinea
 * 2) Section under m. sartorius
 * 3) The last part from the canalis adductorius to the hiatus tendineus

Supply area
A. femoralis and its branches supply the skin of the anterior lower abdomen, the anterior region of the scrotum or labia, all structures of the thigh including the knee joint.

Superficial epigastric artery
A thin branch that ascends and branches into the hypodermis toward the navel.

Arteria circumflexa ilium superficialis
It passes through the subcutaneous tissue of the thigh along the ligaments. inguinale to spina iliaca anterior superior.

Arteriae pudendae externae
Two branches, one of which bends into the pubic landscape and the other sends out:
 * rr. scrotales/labiales anteriores to the external genitalia.

Arteria profunda femoris
A very strong main artery for the muscles of the thigh, which departs laterodorsally about 3–5 cm below the lig. inguinale – but the distance can be quite variable. Broadcasts:
 * a. circumflexa femoris medialis' - passes into the fossa iliopectinea, back to the hip joint and for the pelvitrochanteric muscles, posterior thigh muscles and adductors.
 * a. circumflexa femoris lateralis' - continues under m. rectus femoris and supplies all components of m. quadriceps femoris
 * r. descendens - branch of the artery descending to the knee joint.
 * aa. perforantes' - final branches that pass to the dorsal side through the slits between the adductor attachments. They supply the adductors and all the muscles of the dorsal group, at the same time the aa. nutriciae femoris emerge from them.

Arteria genus descendens
It departs in the canalis adductorius, then it is joined by the vein and the n. saphenus' and together breaks through the membrana vastoadductoria. Its supply area is the muscles of the thigh and it is added to the vascular network of the knee joint - 'rete articulare genus. In addition to the main branches, there are also small branches for the inguinal lymph nodes and muscle branches.
