1. They include the following:
Arteries of lower limb
They include the following:
Femoral, popliteal, obturator, gluteal, tibials and their branches

3. Gluteal Region Superior gluteal artery Inferior gluteal artery
They are branches of the internal iliac artery
They supply the gluteal region
Obturator artery is abranch of the internal iliac artery
It passes through obturator foramen
It supplies the medal side of the upper thigh

4. Femoral Artery
It is the contiuation of the external iliac artery at the mid inguinal point
It descends in the femoral triangle
Then, it continues in the adductor canal
It reaches the adductor hiatus where it becomes the popliteal artery
It supplies all structures in the thigh

6. Femoral Artery Superficial circumflex iliac artery
In the femoral triangle, it gives the following branches:
Superficial circumflex iliac artery
Superficial epigastric artery
External pudendal artery
Deep artery of the thigh
Muscular branches

7. Deep Artery of the Thigh
It is the main artery of the thigh
It gives the following branches
Medial circumflex femoral artery
Lateral circumflex femoral artery which gives a descending branch
Perforating arteries

8. Trochanteric anastomosis
Site: in trochanteric fossa
Formed by:
Branch of sup gluteal art.
Inf gluteal art.
Ascending branch of med circumflex artery.
Importance: a supply of head of femur.

10. The 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

11. The 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.

12. Popliteal Artery
It is the continuation of the femoral artery at the adductor hiatus
It runs through the popliteal fossa
It ends at the lower border of the popliteus muscle by dividing into its terminal branches
It gives the following branches:
Medial superior genicular artery
Lateral superior genicular artery
Medial inferior genicular artery
Lateral inferior genicular artery
Middle genicular artery

13. Popliteal Artery
At the lower end of the popliteus muscle, it divides into:
Anterior tibial artery
Posterior tibial artery which gives the peroneal artery

14. Anastomosis around the Knee Joint
Is made by the following branches:
Descending branch of lateral circumflex femoral
Descending genicular of femoral
Anterior tibial recurrent
Five branches of popliteal artery

15. Anterior Tibial Artery
It is one of the two terminal branches of the popliteal artery
It supplies all structures in the anterior compartment of the leg and perforating branches to lateral compartment
It ends at the midpoint between the malleoli
It continues as Drorsalis Pedis Artery
It gives anterior medial and lateral malleolar branches

16. Posterior Tibial Artery
It is one of the two terminal branches of the popliteal artery
It supplies all structures in the posterior and lateral compartment of the leg
It runs behind and inferior to medial malleolus
It then divides into Medial and Lateral plantar branches
It gives the following branches:
Peroneal artery which gives lateral malleolar and calcaneal branches

17. Dorsalis Pedis Artery
It is the direct continuation of the anterior tibial artery at the midpoint between the malleoli
It gives the following branches:
Lateral tarsal
Medial tarsal
Arcuate
1st dorsal metatarsal
Deep plantar

18. Plantar Arteries The posterior tibial artery divides into:
Lateral plantar
Medial plantar artery which gives the first plantar metatarsal artery
Deep plantar arch is formed by the deep plantar branch of dorsalis pedis artery and lateral plantar artery

19. Surface Anatomy Femoral Profunda Popliteal Posterior tibial Peroneal
Medial plantar
Lateral plantar
Anterior tibial
Dorsalis pedis

20. Veins

21. Arterial pulse

22. Anastomosis in the Lower Limb
Anastomosis between different arterial branches
To ensure blood circulation in the case of occlusion in any artery
Cruciate anastomosis
Geniculate anastomosis
Plantar anastomosis
