ARTERIES OF LOWER LIMB

FEMORAL ARTERY

PROFUNDA FEMORAL ARTERY

PERFORATING BRANCHES

LATERAL FEMORAL

CIRCUMFLEX ARTERY

MEDIAL FEMORAL

CIRCUMFLEX ARTERY

BLOOD SUPPLY OF LOWER LIMB

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

Arterial supply to the posterior thigh and gluteal region.

OBTURATOR ARTERY

ANTERIOR BRANCH

POSTERIOR BRANCH

• CONSIST OF THREE OR FOUR ARTERIES THAT PERFORATE THE ADDUCTOR MAGNUS

• CONTRIBUTING TO THE SUPPLY OF THE MUSCLES IN THE MEDIAL AND POSTERIOR THIGH

PERFORATING BRANCHES

• WRAPS AROUND THE ANTERIOR AND LATERAL SIDE OF THE FEMUR

• SUPPLYING SOME OF THE MUSCLES IN THE LATERAL SIDE OF THE THIGH

LATERAL FEMORAL CIRCUMFLEX

ARTERY

• WRAPS ROUND THE POSTERIOR SIDE OF THE FEMUR

• SUPPLYING THE NECK AND HEAD OF THE FEMUR

MEDIAL FEMORAL CIRCUMFLEX

ARTERY

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

• 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 tibialartery 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.

Venous Drainage of the

Lower Limb

Superficial Veins

Deep Veins

• 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.

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
