Blood supply

Question 1

Question 5

Blood supply to the lower limb course (anterior)

Answer 5

Aorta branches bifurcates into two common iliac arteries (L & R), external iliac artery, femoral artery (muscles), profunda femoris artery (deep artery of thigh), anterior tibial artery, dorsalis pedis artery (dorsal artery of the foot)

Question 6

Blood supply to the lower limb course (posterior) from femoral artery

Answer 6

Femoral artery to the knee, superior medial and lateral genicular branch off before the knee joint, femoral artery becomes popliteal behind the knee, inferior medial and lateral genicular branch off after the knee joint, popliteal artery splits into posterior tibial and fibular, posterior tibial branches into medial and lateral plantar

Question 7

Answer 7

8. Inferior vena cava
9. Common iliac vein
10. External iliac vein
11. Femoral vein
12. Popliteal vein
13. Anterior & posterior tibial veins
14. Dorsal venous arch
15. Lateral & medial plantar veins

Question 8

Answer 8

Dorsalis pedis - in between the EHL and EDL
