Question 1

Which artery is the femoral artery a continuation of?

Answer 1

The external iliac artery

Question 2

At what point does the external iliac artery become the femoral artery?

Answer 2

As it passes underneath the inguinal ligament, through the femoral canal

Question 3

Which is the main arterial supply to the thigh muscles?

Answer 3

profunda femoris artery

Question 4

At what point does the femoral artery become the popliteal artery?

Answer 4

As is passes through the adductor hiatus, from the anterior thigh to the posterior thigh

Question 5

What are the three terminal branches of the popliteal artery?

Answer 5

Anterior tibial artery
Posterior tibial artery
Fibular artery

Question 6

Which artery becomes the dorsalis pedis artery?

Answer 6

Anterior tibial artery

Question 7

Where does the popliteal artery terminate?

Answer 7

At the lower border of the popliteus muscle

Question 8

Describe the course of the posterior tibial artery

Answer 8

Runs along the surface of the deep posterior leg muscles then passes through the tarsal tunnel (posterior to the medial malleolus) along with the tibial nerve.

Question 9

Which artery passes between the tibia and fibula?

Answer 9

anterior tibial artery

Question 10

which artery supplies the lateral leg muscles?

Answer 10

fibular artery

Question 11

name the three branches of the profunda femoral artery

Answer 11

lateral femoral circumflex artery
perforating branches
medial femoral circumflex artery

Question 12

which artery supplies the head and neck of the femur?

Answer 12

medial femoral circumflex artery

Question 13

Which superficial vein drains into the femoral vein?

Answer 13

Great saphenous vein

Question 14

Which superficial vein drains into the popliteal vein?

Answer 14

Small saphenous vein

Question 15

Describe the course of the great saphenous vein

Answer 15

• passes anteriorly to the medial malleolus of the ankle
• runs up the medial side of the leg
• passes posteriorly to the medial condyle of the knee
• drains into the femoral vein

Question 16

Describe the course of the small saphenous vein

Answer 16

• passes posteriorly to the lateral malleolus of the ankle
• runs up the posterior side of the leg
• passes between the two heads of gastrocnemius and drains into the popliteal vein in the popliteal fossa

Question 17

Which is the main vein responsible for draining the thigh?

Answer 17

Deep vein of the thigh

aka profunda femoris vein
