3Gluteal Region Superior gluteal artery Inferior gluteal artery They are branches of the internal iliac arteryThey supply the gluteal regionObturator artery is abranch of the internal iliac arteryIt passes through obturator foramenIt supplies the medal side of the upper thigh
4Femoral ArteryIt is the contiuation of the external iliac artery at the mid inguinal pointIt descends in the femoral triangleThen, it continues in the adductor canalIt reaches the adductor hiatus where it becomes the popliteal arteryIt supplies all structures in the thigh
6Femoral Artery Superficial circumflex iliac artery In the femoral triangle, it gives the following branches:Superficial circumflex iliac arterySuperficial epigastric arteryExternal pudendal arteryDeep artery of the thighMuscular branches
7Deep Artery of the Thigh It is the main artery of the thighIt gives the following branchesMedial circumflex femoral arteryLateral circumflex femoral artery which gives a descending branchPerforating arteries
8Trochanteric anastomosis Site: in trochanteric fossaFormed by:Branch of sup gluteal art.Inf gluteal art.Ascending branch of med circumflex artery.Importance: a supply of head of femur.
10The cruciate anastomosis is a circulatory anastomosis in the upper thigh of the inferior gluteal artery, the lateral and medial circumflex femoral arteries, and the first perforating artery of the profunda femoris artery
11The route of blood is through the internal iliac, to the inferior gluteal artery, to a perforating branch of the deep femoral artery, to the lateral circumflex femoral artery, then to its descending branch into the superior lateral genicular artery and thus into the popliteal artery.
12Popliteal ArteryIt is the continuation of the femoral artery at the adductor hiatusIt runs through the popliteal fossaIt ends at the lower border of the popliteus muscle by dividing into its terminal branchesIt gives the following branches:Medial superior genicular arteryLateral superior genicular arteryMedial inferior genicular arteryLateral inferior genicular arteryMiddle genicular artery
13Popliteal ArteryAt the lower end of the popliteus muscle, it divides into:Anterior tibial arteryPosterior tibial artery which gives the peroneal artery
14Anastomosis around the Knee Joint Is made by the following branches:Descending branch of lateral circumflex femoralDescending genicular of femoralAnterior tibial recurrentFive branches of popliteal artery
15Anterior Tibial Artery It is one of the two terminal branches of the popliteal arteryIt supplies all structures in the anterior compartment of the leg and perforating branches to lateral compartmentIt ends at the midpoint between the malleoliIt continues as Drorsalis Pedis ArteryIt gives anterior medial and lateral malleolar branches
16Posterior Tibial Artery It is one of the two terminal branches of the popliteal arteryIt supplies all structures in the posterior and lateral compartment of the legIt runs behind and inferior to medial malleolusIt then divides into Medial and Lateral plantar branchesIt gives the following branches:Peroneal artery which gives lateral malleolar and calcaneal branches
17Dorsalis Pedis ArteryIt is the direct continuation of the anterior tibial artery at the midpoint between the malleoliIt gives the following branches:Lateral tarsalMedial tarsalArcuate1st dorsal metatarsalDeep plantar
18Plantar Arteries The posterior tibial artery divides into: Lateral plantarMedial plantar artery which gives the first plantar metatarsal arteryDeep plantar arch is formed by the deep plantar branch of dorsalis pedis artery and lateral plantar artery
