thigh and knee Flashcards
Bony points
medial and lateral condyles/ epicondyles of the femur medial and lateral condyles of the tibia adductor tubercle patella tibial tuberosity
Knee joint
- hinge joint - flexion, extension
- lined with hyaline cartilage
- has medial/ lateral menisci (fibrocartilage) to deepen articular surface of tibia (stabilize) and act as a shock absorber
knee ligaments
collateral ligaments: stabilise hinge joint
- medial collat: medial epi femur to medial condyle tibia
- lateral collat: lateral epi femur to lateral fibular head
cruciate ligaments
- anterior: prevents anterior dislocation
- posterior - prevents post dislocation
patella tendon
continuation of quadriceps femoris tendon - attaches to the tibial tuberosity
superior tibiofibular joint
- plane joint - bones glide over each other to create movement
- supported by hyaline cartilage, TF ligaments and lateral collateral lig
Rectus femoris
A: extension of the knee
O: AIIS
I: tibial tuberosity
N: femoral
vastus medialis
A: extension of the knee
O: medial lip of linea aspera
I: tibial tuberosity
N: femoral
vastus lateralis
A: extension of the knee
O: lateral lip of linea aspera, gluteal tuberosity, greater trochanter
I: tibial tuberosity
N: femoral
Iliotibial tract
A: acts as an extensor, abductor and lateral rotator of the hip and helps stabilize the knee joint
O: iliac tubercle
I: lateral tibial condyle
sartorius
A: flex and laterally rotate hip, flex and medially rotate flex knee
O: ASIS
I: prox, medial shaft of tibia
N: femoral
bicep femoris
A: Flex and laterally rotate the flexed knee, (long head) extends the hip
O: long head: ischial tuberosity, short head: lateral lip of linea aspera
I: head of fibula
N: sciatic – tibial branch
semimembranosus
A: Flex and medially rotate the flexed knee, extend the hip
O: ischial tuberosity
I: posterior medial condyle of tibia
N: sciatic – tibial branch
semitendinosus
A: Flex and medially rotate flexed knee, extend the hip
O: ischial tuberosity
I: medial shaft of tibia
N: sciatic – tibial branch
gastrocnemius
A: flex the knee and planter flex the ankle
O: femoral condyles
I: calcaneus
N: tibial
soleus
A: plantar flex the ankle
O: soleal line, prox/posterior tibia surface
I: calcaneus
N: tibial
