Answer 12

the tibial

lateral plantar

Question 15

what cutaneous nerve supplies the lateral ankle?

saphenous

Question 16

outline the origins of :

FHL, FDL and TP

Answer 16

TP: interrosseus + tibia + fibula

FHL: fibula + interosseus

FDL: JUST medial tibia

Question 17

what innervates the skin between the 1st and 2nd toes?

Answer 17

terminal branches of deep fibula. can used to monitor the status of deep fibular nerve (i.e. foot drop)

Question 18

where does the deep fibula nerve go?

Answer 18

right down over the ant surface of the leg with the anterior tibial artery and follows it over the ankle into the foot between the 1st and 2nd toes

deep fibular

Question 21

where do EHB and EDB originate from?

Answer 21

superolateral aspect of calcaneus

Question 22

what innervates flexor digitorum brevis?

Answer 22

medial plantar

Question 23

what is the plantar equivalent of the “arcuate “ artery

Answer 23

deep plantar arch

Answer 24

abductor halluces

FDB

Question 25

what innervates FDB?

Answer 25

Answer 27

superior fibular retinaculum inferior fibular retinaculum

Question 28

which is more superficial: FDL or FDB?

Answer 28

FDB runs on top of FDL

Question 29

where does the great saphenous vein run? in comparison to the small saphenous vein?

Answer 29

great runs more anteromedially down the leg into the foot anteromedially. small runs posteriorly along the tibia and postero- laterally into the foot
