Blood Supply of the Lower Limb

By Mahes Arvin


1)The deep femoral artery usually:
 A.     Gives rise to the medial femoral circumflex artery which is especially important because it supplies the head of the femur.
B.      Has a lateral femoral circumflex branch with supplies the greater trochanter of the femur.
C.      Is accompanied by the nerve to the vastus medialis.
D.      Gives rise to branches that supply the hamstring muscles.
E.      The deep femoral artery branches off from the common femoral artery at a point known as the femoral triangle.

2)The arteries usually supplying the neck and head of the femur include the:
 A.     Inferior gluteal artery.
B.      Artery of the ligament of the head.
C.      Medial femoral circumflex artery.
D.      Lateral femoral circumflex artery.
E.      Perforating arteries.

3)The dorsalis pedis artery usually:
 A.     Is a continuation of the anterior tibial artery on the dorsum of the foot.
B.      Gives rise to the arcuate artery which, in turn, sends branches to the medial and lateral sides of all of the toes.
C.      Gives rise to a deep plantar artery that, in turn, sends branches to all of the toes.
D.      Gives rise to branches that supply the ankle joint.
E.      Along its course, it is accompanied by a vein,the small saphenous vein.
4)The plantar arterial arch has connections directly with the:
 A.     Metatarsal arteries.
B.      Lateral plantar artery.
C.      Superficial branch of the medial plantar artery.
D.      Perforating branches to the dorsum of the foot.
E.      Posterior tibial artery.

5)The great saphenous vein:
A.      When it is removed and inserted as a coronary bypass, it is reversed, so that the cusps do not obstruct blood flow.
B.      It is located about ten cm. (a handbreadth) posterior to the medial border of the patella.
C.      It passes anterior to the medial malleolus.
D.      It perforates the femoral sheath.
E.      It is accompanied by the sural nerve in the leg.

6)Profunda femoris artery:
A.      Passes deep to both femoral artery and vein.
B.      Has a transverse medial branch.
C.      It is the main blood supply to the posterior compartment of the thigh.
D.      It lies between the adductor brevis and adductor magnus.
