The knee Flashcards
Patella
sesamoid bone, has patellar tendon, forms patellofemoral joint with femur
base is the top curved part
apex the pointy bottom bit
articular facets
depressions for lateral femoral & medial femoral condyles to fit in
Fibula
Head of fibula
shaft of fibula
lateral malleolus on fibula
Tibia
medial malleolus
lateral & medial tibial condyles
Tibial tuberosity
superior tib fib joint
where tib and fib join
intercondylar eminence
elevated area between the 2 condyles of one bone
anterior crest
ridge located just under the skin, extends from tibial tuberosity to medial malleolus
tibia interosseous border
tibias sharp edged lateral margin that provides attachment for the interosseous membrane
Quadriceps
rectus femoris
vastus medialis
vastus intermedius
vastus lateralis
Hamstrings
Biceps femoris
Semi membranosus
Semi tendinosus
menisci
lateral & medial meniscus inside knee cross over used for shock absorption
ACL & PCL
anterior cruciate ligament
posterior cruciate ligament
stop over extension of knee
located within the joint
lateral and medial collateral
ligament either side of knee
help with stability
muscles that flex the knee
semimembranosus - ischial tuberosity to medial condyle of tibia (sciatic nerve L5,S1,S2)
semitendinosus - ischial tuberosity to tibial tuberosity ( sciatic nerve L5,S2,S2)
Bicep femoris - long head ischial tuberosity to lateral condyle of tibia (sciatic nerve L5, S1, S2)
muscles that extend the knee
rectus femoris - AIIS to tibial tuberosity (femoral nerve L2-L4)
vastus medialis - intertrochanteric line to tibial tuberosity (femoral L2-L4)
vastus intermedialis - upper shaft of femur to tibial tuberosity (femoral nerve L2-L4)
Vastus lateralis - greater trochanter to tibial tuberosity (femoral nerve L2-L4)
