L9 bones & joints of the gluteal region, thigh, and knee Flashcards
(36 cards)
bony features that are
- found at the lateral surface of the ilium’s wings
- divides the lateral surface for the different attachment points of the gluteal muscles
gluteal lines
this hip bone is
- found ant-inf
- has a body, sup & inf ramus
ischium
true or false
post part of femoral shaft is smooth & has no bony features
false
the tibiofemoral joint is a ____ joint that functions as a ____ joint due to the presence of ____ ligs
bicondylar
hinge
collateral
what’s the angulation of the femoral neck in relation to the femoral shaft?
frontal & transverse plane
when tibia is fixed, how should the femur rotate to start knee flexion?
laterally
meniscus that’s C-shaped and has an attachment to the medial collateral lig
medial
during the last 15-20 degrees of knee extension, how does the tibia rotate on a fixed femur rotate to achieve the screw home mechanism?
laterally
name the weight bearing & the non weight bearing joints of the knee complex
weight bearing - tibiofemoral
non weight bearing - patellofemoral
the spiral line from the lesser trochanter of the femur continues post as the ____
gluteal tuberosity
ACL prevents ___ displacement of femur on a fixed tibia
post
the wing of the ilium’s ______ surface has a concave shape, which produces the ____ (site of origin for the iliacus muscle)
inner
iliac fossa
the wing of the ilium’s ______ surface has a convex shape, and provide’s attachments to the ___
external
gluteal muscles
the 3 hip bones are united by the ___ of the ___
triradiate cartilage
- Y shaped => “tri”
acetabulum
the deficiency of the acetabulum in its lower margin
acetabular notch
the non articulating surface of the acetabulum, that serves as the attachment site for the ligament of the femoral head (connects the acetabulum directly to the femoral head)
acetabular fossa
the collateral ligaments are __ joints that reinforce what movements?
hinge
hinge like
attachment of the medial collateral lig sup & inf
sup - medial condyle (femur)
inf - tibia (mid upper end)
which ligament resists excess knee valgus (lat deviation)?
MCL
ligaments found within the intercondylar fossa
cruciate ligs
ACL prevents ___ displacement of tibia on a fixed femur
ant
PCL prevents ___ displacement of femur on a fixed tibia
ant
PCL prevents ___ displacement of tibia on a fixed femur
post
why is the lateral meniscus more mobile than the medial one?
cuz the lat one is unattached to the capsule (somehwere in tibia?)
