25
does rectus femoris attach to ASIS or AIIS
AIIS
26
what soft tissue structure lies superficial to the vastus lateralis
IT band
27
what is the VMO and what is it impt for
vastus medialis oblique distal portion of the VM important for patellar tracking (if weak, patella pulls laterally, if strong--pulls patella more medially)
28
most common location for patellar injury
laterally
29
where is popliteus found
very deep, posterior knee
30
does popliteus touch the fibia
no
31
what is the main function of the popliteus
unlocks the knee by rotation femur on fixed tibia
32
to straighten knee/ lock, which way does the tibia rotate
quads straighten, bones do outward twist to lock
33
to unlock knee, which way does the tibia rotate
popliteus unlocks by medially/inward twist
34
where does superior gluteal nerve run to
TFL???
35
where does the inferior gluteal nerve run to
gluteus maximus
36
how many hamstring muscles are biarticulate
3 of 4
37
which hamstring muscle is not biarticulate
biceps femoris
38
what are the hamstring muscles
semitendinosus, semimembranosus, biceps femoris (long/short heads)
39
what are the lateral 2 hamstring muscles and what are the medial 2
lateral: biceps femoris medial: semitendinosus, semimembranosus (both semis go medially)
40
what makes up the pes anserine
gracilis, semitendinosus, sartorius
41
what is the order of the pes anserine, what are the nerves, and what's the saying
SGT FOT sartorius, gracilis, semitendinosus femoral, obturator, tibial nerve medial to lateral
42
when does the femoral artery become the popliteus artery
after passing through the adductor hiatus in the adductor magnus
43
where do clots happen in veins
deep vein (deep vein thrombosis)
44
where are saphenous structures
medial leg
45
what is a femoral hernia caused by
abdominal viscera protrudes through the femoral ring at the saphenous opening
46
popliteal fossa contents
popliteal artery and vein, tibial nerve AVN
47
which nerve does lateral and which stays straight: tibial, common fibular
common fibular nerve goes lateral tibial nerve stays straight
48
whats the parent structure of common fibular nerve
sciatic nerve
49
where are sural structures located
lateral lower leg
50
genu varum and valgum laymans term
varum: bowleg (decreased Q angle) valgum: knock knee (increased Q angle)
51
what is the Q angle and do males or females have a bigger angle
difference between the line of gravity and where the femur runs/angle of the femur female have a bigger Q angle bc hips are wider
52
what movement does the LCL restrict
53
what movement does the MCL/ tibia collateral ligament resist
54
the oblique popliteal ligament is an extension of what tendon
55
what movement does the ACL resist
prevents anterior displacement of tibia hyperextension of knee joint
56
what movement does the PCL resist
prevents anterior displacement of the femur on the tibia prevents hyperflexion of knee
57
ACL two bundles
AM and PL anteromedial, posterolateral
58
what part of the meniscus has blood
very outer part
59
what meniscus is bigger
medial
60
which meniscus is circular, smaller, and more freely moving
lateral
61
which meniscus is c-shaped, wider posteriorly than anteriorly, and less mobile
medial
62
which meniscus is more likely to be injured
medial
63
what three structures are injured with an unhappy triad
MCL, ACL, and medial menisc
