2. BLOOD SUPPLY OF LOWER LIMB

3. The anatomical course of the femoral artery, and its branches.

4. Arterial supply to the posterior thigh and gluteal region.

5. POPLITEAL ARTERY Continuation of the femoral artery At the lower border of the popliteus , dividing into Anterior tibial artery Posterior tibial artery Branches Genicular branches- knee joint Muscular branches- harmstring,GN , soleus,plantaris Cutaneous branches

6. the anterior tibial artery, passes anteriorly between the tibia and fibula, through a gap in the  interosseous membrane . It then moves inferiorly down the leg. It runs down the entire length of the leg, and into the foot, where it becomes the dorsalis pedis artery. The posterior tibial artery continues inferiorly, along the surface of the deep muscles (such as tibialis posterior). It accompanies the tibial nerve in entering the sole of the foot via the tarsal tunnel . During the descent of the posterior tibial artery in the leg, the fibular artery arises. This artery moves laterally, penetrating the lateral compartment of the leg. It supplies muscles in the lateral compartment, and adjacent muscles in the posterior compartment.

7. Division into plantar arteries in sole Peroneal branch given to lateral compartment Post: tibial A Lat : plantar A Med: Plantar A

8. Arterial supply to the anterior leg, via the anterior tibial artery. Arterial supply to the posterior leg, via the popliteal artery and branches.

9. Ant: tibial Artery Dorsalis pedis artery

10. Dorsalis pedis artery Tendon of EHL m/s

11. SUPERFICIAL VEINS The superficial veins commence in a dorsal venous arch which lie on the dorsum of the foot. It receives most of the blood from the sole.

12. DEEP VEINS The dorsal venous arch in the foot is primary drained by superficial veins. However, perforating veins from this structure move deep into the leg, forming the anterior tibial vein. Medial and lateral plantar veins form posterior tibial and fibular veins. All three of these deep veins combine to form the popliteal vein at the knee
