24
Q

sartorius

A

O: ASIS & interspinous fossa
is: pes anserinus

A: hip flexion, lateral rotation& abduction knee flexion, medial rotation of leg with knee flexed
IN: femoral nerve anterior division

25
Q

A: knee extension &flip flexion(both tg)
in: femoral nerve posterior division

26
Q

vastus lateralis

A

o: upper part of intertrochanteric line
anterior/inferior borders of greater trochanter
lateral edge of gluteal tuberosity

ins: base &lateral border of patella
patellar ligament &lateral patellar retinaculum

A: knee extension
IN: femoral nerve post division

27
Q

vastus medialis

A

A: knee extension & prevents lateral patellar tracking (VMO)

in: femoral nerve post div

28
Q

vastus intermedius

A

A: knee extension
IN: femoral nerve post div

29
Q

what forms the patellar ligament

A

tendons of quadriceps femoris muscle group

extends from patella to distal 1/2 of tibial tuberosity

30
Q

articularis genu

A

o: femur
ins: suprapatellar bursa

A: stabilizes bursa
IN: twig from femoral N branch to vastus intermedius

31
Q

What are the boundaries of the femoral triangle?

A 
Lateral: sartorius
Medial: adductor longus
Base: Inguinal ligament
Floor: pectineus & iliopsoas
Roof: fascia lata (+ subcutaneous tissue and skin)
32
Q

What are the structures found within the femoral triangle?

A

femoral artery and vein

great saphenous vein

33
Q

what is femoral sheath composed of anteriorly and posteriorly

A

transversalis fascia anteriorly

iliacus fascia posteriorly

34
Q

what is clinical relevance of empty space in femoral sheath

A

femoral hernias

35
Q

What are the walls of the adductor canal?

A

Roof: sartorius
Anterolateral: vastus medialis
Posterior: adductor longus & magnus

36
Q

What are the contents of the adductor canal?

A

Femoral artery & vein
Saphenous nerve
Nerve to vastus medialis

***femoral artery is anterior to vein at the proximal end of the canal

37
Q

Where does the adductor canal end?

A

inferiorly at adductor hiatus

38
Q

femoral artery is __ vein at proximal end of adductor canal

A

anterior

39
Q

where does adductor canal end

A

adductor hiatus

40
Q

Once the femoral artery and vein pass through the adductor hiatus, what are they called?

A

popliteal vessels

41
Q

what is the IT band

thickening of the fascia lata along the lateral side of the thigh

42
Q

what is proximal attachment of IT band

A

iliac crest

43
Q

what is distal attachment of IT band

A

lateral tibial condyle, femur, head of fibula, aponeurosis of vastus lateralis

44
Q

Where does the IT band attach along much of its length?

A

lateral intermuscular septum

45
Q

What are the two muscles that insert into the IT tract?

A

Gluteus Maximus and tensor fascia latae and its superficial fibers which acts and their aponeurosis

46
