Leg Vascular and Neural Elements

Question 1

when does the femoral artery become the popliteal artery

Answer 1

when it passes through the adductor hiatus

Question 2

what are the branches of the popliteal artery

Answer 2

anterior tibial

posterior tibial

Question 3

anterior tibial artery

Answer 3

passes through interosseous membrane

runs w/ deep fibular nerve b/w tibialis anterior and extensor digitorum longus

continues in the foot as dorsalis pedis

Question 4

posterior tibial artery

Answer 4

runs b/w superficial and deep layers of the posterior compartment

just deep to the transverse intermuscular septum

runs with the tibial nerve

terminal branches in the foot

branches off

Question 5

what does the posterior tibial artery branch off into in the leg

Answer 5

fibular artery

circumflex fibular artery

Question 6

circumflex fibular artery

Answer 6

car arise from the anterior or posterior tibial artery

varies from person to person

Question 7

what does the posterior tibial artery branch off into in the foot

Answer 7

medial plantar

lateral plantar

Question 8

what are the superficial veins of the leg

Answer 8

great saphenous (long)

small saphenous (short)

Question 9

great saphenous vein

Answer 9

long

runs with saphenous nerve

medial aspect of the leg and thigh

Question 10

small saphenous vein

Answer 10

short

runs with sural nerve

in posterior leg

goes into popliteal fossa

Question 11

deep veins of the leg

Answer 11

accompany arteries

popliteal vein

Question 12

nerves of the leg

Answer 12

saphenous

sural

tibial

common fibular

Question 13

saphenous nerve

Answer 13

from femoral nerve

sensory to medial aspect of leg

Question 14

sural nerve

Answer 14

from tibial and common fibular nerves

runs with small saphenous vein

sensory to posterior and lateral leg

Question 15

tibial

Answer 15

from sciatic nerve

motor to posterior compartment of leg

Question 16

common fibular nerve

Answer 16

sensory to the knee

at risk for injury

branches into 2 nerves

Question 17

how is the common fibular nerve at risk for injury

Answer 17

it is near the head of the fibula

if there is a fracture, it can be injured

leads to drop foot

Question 18

what are the two branches of the common fibular nerve

Answer 18

superficial and deep

Question 19

superficial fibular nerve

Answer 19

muscles of lateral compartment

sensory to anterolateral aspect of middle and deep leg

Question 20

deep fibular nerve

Answer 20

motor to anterior compartment of leg
