what does the superficial fibular innervate

A

fibular msucles (brev and longus)

29

what do the deep fibiular innervate

A

Anterior leg

30
Q

true ro false: the superficial and deep fibular stay anteriorly

A

true

31
Q

is the sural nerve inenrvation or sensory

A

sensory

32
Q

arteries

A

abdominal artery
common illiac
internal and external illiac
femoral (deep femoral and medial.lateral femoral circumflex)
popliteal (genicular)
anterior tibial (dorsalis pedis)
posterior tibial (fibular and then medial and lateral and deep arches)

33
Q

where is common illiac arteries

A

L4

34
Q

where are external illiac arteries

A

L5/S1

35
Q

what comes off the external illiac

A

femoral artery

36
Q

what are the branches of the femoral artery

A

deep femoral
lateral and medial femoral circumflex
perforating arteries

37
Q

what is the fucntion of the perforarting arteries

A

off deep femoral and will go through the adductor and will supply the posterior thigh

38
Q

where do the medial and lateral femoral circumflexes arteries and veins go>

A

around neck of the femur

39
Q

when does it become femoral (veins and artery)

A

past inguinal line

40
Q

what does the femoral artery turn into

A

popliteal artery

41
Q

what branches off the popliteal artery

A

genicular arteries
posterior tibial artery
anterior tibial artery

42
Q

where does the femoral artery pass

A

adductor canal

43
Q

where does the anterior tibial artery perforate

A

the interosseous membrane

44
Q

what does the posterior tibial artery split into

A

fibular
medial and lateral plantar
into plantar arch

45
Q

what does anterior tibial artery split into

A

dorsalis pedis artery

dorsal arch

46
Q

where does the saphenous vein go and insert

A

starts and stays medial dumps into femoral

47
Q

what is the saphenous vein opening

A

allows saphernous vein to exit the fascia amnd supply medially

48
Q

what is the cribriform fascia

A

fascia that closes the saphenous opening and holds the saphenous vein

49
Q

are great and small saphenous veins venous commitantes

A

no

50
Q

what are the veins

A

inferior vena cava
common illiac vein
internal and external illiac vein
femoral vein (great saphenous and deep femoral)
popliteal vein (small saphenous)
>posterior tibial (fibular and medial and lateral p[lantar)
>anterior tibial (dorsalis pedis)

51
Q

is small saphenous vein medial or lateral

A

lateral

52
Q

does the small saphenous vein go all the way down

A

no, it is lateral and stops near knee
