Q

what does ramus mean

A

a projection or arch

20
Q

longest bone in the body
longest muscle in the body

A

longest bone: femur
longest muscle: sartorius

21
Q

without the patella, the femur…

A

knee extension would be limited

22
Q

patella shape

A

sesamoid

23
Q

tibial plateau injuries

A

pedestrian auto injuries

24
Q

what is the ligament that passes in the acetabulum

A

ligament of head of femur

25
Q

what is the parent structure of the artery to head of femur?

A

obturator artery

26
Q

what ligament @ femoral head forms the y
what movement does it resist

A

iliofemoral ligament
limits extension

27
Q

knee joint bones

A

patella, tibia, femur

28
Q

the most important stabilizing muscle is…

A

the quadratus femoris

29
Q

what position is the most stable position of the knee joint?

A

knee extension

30
Q

adductor canal

A

femoral nerve
femoral artery
femoral vein

31
Q

which one of the quads starts posteriorly?

A

vastus lateralis [PA @ lateral lip of linea aspera]

32
Q

where can the IT band get stuck

A

vastus lateralis

33
Q

most common patellar dislocation?

what muscle do you have to straighten to pull the patella medially

A

lateral
VMO

34
Q

closed chain - to “lock” knee

A

to lock the knee, the femur medially rotates on fixed tibia to allow quads to extend the knee

35
Q

closed chain - to “unlock” knee

A

to unlock the knee, POPLITEUS CONTRACTS, the femur laterally rotates on fixed tibia so flexion can happen

36
Q

open chain - to “lock” knee

A

the knee locks by laterally rotating tibia on fixed femur to allow quads to extend

37
Q

closed chain - to “unlock” knee

A

the unlock knee, POPLITEUS CONTRACTS, medial rotation the tibia to fixed femur so flexion can occur

38
Q

what way does the popliteus twist to unlock the knee

how many degrees do the tib and fib twist to straighten the knee

A

inward!

3-4 degrees

39
Q

neurovascular bundle

A

superior gluteal artery and nerve

40
Q

where does the femoral hernia appear

A

at the saphenous opening, the small intestine can protrude through the femoral ring.
appears as a mass in the femoral triangle

41
Q

popliteal fossa
contents and borders

A

semitendinosus [medial]
biceps femoris [lateral]
AVN
popliteal artery
popliteal vein
tibial nerve

42
Q

what motion does the ACL limit

A

prevents anterior dislocation of the tibia on the femur, prevents hyperextension of the knee

43
Q

what motion does the PCL limit

A

prevents anterior displacement of the femur on the tibia

prevents posterior displacement of the tibia on the femur

prevents hyperflexion of the knee joint

44
Q

the crossing of the cruciate ligaments serve as a..

A

pivot for rotatory movements at the knee

45
Q

what are the two bundles of the ACL

A

anteromedial AM
posterolateral PL
