ILS 10 Flashcards
bones of the knee joint include:
patella and tibia
which bone is not directly involved in knee joint formation
fibula
largest sesamoid bone
patella
located within the tendon of the quadriceps femoris
patella
articulates with the femur but not with the tibia
tendon of the quadriceps femoris
the patella is the ___ located ___ and attaches to the ___ via ___ and functions to ___ as it passes across the ___ and functions to ___ thereby ___
largest sesamoid bone;
within the tendon of the quadriceps femoris;
tibial tuberosity;
patellar ligament;
obviate wear and attrition on the quadriceps tendon;
trochlear groove;
increase the angle of pull of the quadriceps femoris;
magnifying its power
the tendon of the quadriceps femoris articulates with the
femur
attaches to the tibial tuberosity by a continuation of the quadriceps tendon
patella
continuation of the quadriceps tendon is called
the patellar ligament
the patellar ligament is a continuation of the
quadriceps tendon
functions to obviate wear and attrition on the quadriceps tendon
patella
passes across the trochlear groove
patella
increases the angle of pull of the quadriceps femoris, thereby magnifying its power
patella
the weight-bearing medial bone of the leg
tibia
has the tibial tuberosity into which the patellar ligament inserts
tibia
the medial and lateral condyles of the tibia articulate with the
condyles of the femur
projection with a malleolar groove for the tendons of the tibialis posterior and flexor digitorum longus muscles
the medial malleolus of the tibia
has a groove for the tendon of the flexor hallucis longus muscle
tibia
groove posterolateral to the malleolus groove
groove for the tendon of the flexor hallucis longus muscle
provides attachment for the deltoid ligament of ankle joint
tibia
the patellar ligament inserts into the
tibial tuberosity
articulate with the condyles of the femur
the medial and lateral condyles of the tibia
the groove for the tendon of the flexor hallucis longus muscle is
posterolateral to the malleolus groove
the medial malleolus of the tibia has a malleolus groove for the
tendons of the tibialis posterior and flexor digitorum longus muscles
the tibia is the ___ that provides attachment for the ___
weight-bearing medial bone of the leg;
deltoid ligament of ankle joint
has little or no function in weight- bearing but provides attachment for muscles
fibula
its apex (head) provides attachment for the fibular collateral ligament of the knee joint
fibula
the ___ of the fibula provides attachment for the ___ of the ___
apex;
fibular collateral ligament;
knee joint
tibial plateau includes the
intercondylar eminence
the intercondylar eminence is part of the
tibial plateau
largest and most complicated joint
knee joint
a condylar type of synovial joint between two condyles of the femur and tibia
knee joint
a saddle joint between the femur and the patella
knee joint
is encompassed by a fibrous capsule that is rather thin, weak, and incomplete
knee joint
is attached to the margins of the femoral and tibial condyles and to the patella and patellar ligament
fibrous capsule of the knee joint
surrounds the lateral and posterior aspects of the knee joint
fibrous joint capsule
permits flexion, extension, and some gliding and rotation in the flexed position of the knee
knee joint
full extension of the knee is accompanied by ___ of the ___ on the ___, pulling all ligaments ___
medial rotation;
femur;
tibia;
taut
the knee joint is the ___ that is considered a ___ joint between ___ and also a ___ joint between ___
largest and most complicated joint; synovial; two condyles of the femur and tibia; saddle-joint; the femur and the patella
the fibrous capsule of the knee is rather ___ but attached to the ___ and to the ___ and surrounds the ___
thin, weak, and incomplete;
margins of the femoral and tibial condyles;
patella and patellar ligament;
lateral and posterior aspects of the joint
mobile and weight-bearing, hence commonly injured
knee joint
stability of the knee joint depends on the
strength of the surrounding muscles, particularly the quadriceps
the knee joint is stabilized laterally by the
biceps and gastrocnemius (lateral head) tendons, the iliotibial tract, and the fibular collateral ligaments
the knee joint is stabilized medially by the
sartorius, gracilis, gastrocnemius (medial head), semitendinosus, and semimembranosus muscles and the tibial collateral ligament
why is the knee joint mechanically unstable
idk
cruciate ligaments
intracapsular extrasynovial ligaments
intrascapular extrasynovial ligaments
cruciate ligaments
has opening posterior to lateral tibial condyle
fibrous knee joint capsule
is completed anteriorly by the quadriceps tendon, patella, and patellar tendon
fibrous knee joint capsule
passage of popliteus tendon
opening posterior to lateral tibial condyle in the fibrous knee joint capsule
the opening posterior to lateral tibial condyle allows the ___ to pass through
popliteus tendon
lines all surfaces, not covered by articular cartilage
synovial membrane
reflects anteriorly covering the cruciate ligaments and infrapatellar fat pad
synovial membrane of the knee joint
divides the articular cavity into right and left compartments
synovial membrane
infrapatellar fat pad
median infrapatellar synovial fold
the synovial membrane of the knee joint reflects ___ and divides the ___ into ___
anteriorly covering the cruciate ligaments and infrapatellar fat pad;
articular cavity;
right and left compartments
