16
Q

outline the origins of :
FHL, FDL and TP

A

TP: interrosseus + tibia + fibula

FHL: fibula + interosseus

FDL: JUST medial tibia

17
Q

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

A

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

18
Q

where does the deep fibula nerve go?

A

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

19
Q

where to TA, EHL and EDL originiate? each have 2

A

TA: tibia + interossues

EHL: fibula + interosseus

EDL: prox med fibula + lateral tibial condyle

20
Q

what innervates EDB?

A

deep fibular

21
Q

where do EHB and EDB originate from?

A

superolateral aspect of calcaneus

22
Q

what innervates flexor digitorum brevis?

A

medial plantar

23
Q

what is the plantar equivalent of the “arcuate “ artery

A

deep plantar arch

24
Q

what else originates from the same place that the plantar aponeurosis(pfascia) originates i.e. plantar calc @ ant calcaneal tubercle

A

abductor halluces
FDB

25
Q

what innervates FDB?

A

medial plantar nerve from tibial nerve

26
Q

what innervates quadratus plantae?

A

lateral plantar nerve

27
Q

what do we call the retinaculum that holds in the tendons laterally (peroneals)

A

superior fibular retinaculum

inferior fibular retinaculum

28
Q

which is more superficial: FDL or FDB?

A

FDB runs on top of FDL

29
Q

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

A

great runs more anteromedially down the leg into the foot anteromedially.

small runs posteriorly along the tibia and postero- laterally into the foot
