Muscles That Move The Knee Flashcards
Sartorius action
Hip: flex, lateral rotation, abduction of the thigh
Knee: flexion and medial rotation
Pelvis: posterior tilt
Rectus femoris location
O:AIIS
I: tibial tuberosity via patellar ligament
N:femoral nerve
Rectus femoris action
Flexion of the femur and extension of the knee
Sartorius (O,I,N)
O: ASIS
I: pes anserine-prox antromedial aspect of tibia
N: femoral nerve
Vastus intermedius location
O: anterior shaft and the linea aspera
I:tibial tuberosity via the patellar ligament
N: femoral nerve
Vastus intermedius action
Extension of the knee
Biceps femoris location
O: long head-Ischial tuberosity = short head-linea aspera
I:fibular head/lateral tibial condyle
N: sciatic nerve
Biceps femoris action
Hip: extends, laterally rotates and adducts the thigh
Knee: flexion and lateral rotation of the flexed knee
Vastus lateralis location
O: post aspect of the mid shaft of femur(linea aspera)
I: tibial tuberosity via patellar ligament
N: femoral nerve
Vastus lateralis action
Extension of the knee
Vastus medialis location
O: post aspect of mid shaft- linea aspera
I: tibial tuberosity via patellar ligament
N: femoral nerve
Vastus medialis action
Extension of knee
Semitendinosus location
O: ischial tuberosity
I: pes anserine-prox anteromedial aspect of tibia
N: sciatic nerve
Semitendinosus action
Hip: extension and medial rotation of the thigh
Knee: flexion and medial rotation of the thigh
Semi membranous location
