(28 cards)
rectus femoris action
knee extension
steadies hip joint
helps iliopsoas flex hip joint
rectus femoris PA
anterior inferior iliac spine
ilium
rectus femoris DA
quadriceps tendon to tibial tuberosity via patellar ligament
rectus femoris nerve innervation
femoral nerve L2, L3, L4
vastus lateralis action
knee extension
vastus lateralis PA
greater trochanter
lateral lip of linea aspera
vastus lateralis DA
quadriceps tendon to tibial tuberosity via patellar ligament
also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)
vastus lateralis nerve innervation
femoral nerve L2, L3, L4
vastus medialis action
knee extension
vastus medialis PA
intertrochanteric line
medial lip of linea aspera
vastus medialis DA
quadriceps tendon to tibial tuberosity via patellar ligament
also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)
vastus medialis nerve innervation
femoral nerve L2, L3, L4
vastus intermedius action
knee extension
vastus intermedius PA
anterior and lateral femoral shaft
vastus intermedius DA
quadriceps tendon to tibial tuberosity via patellar ligament
vastus intermedius nerve innervation
femoral nerve L2, L3, L4
semitendinosus action
hip extension
knee flexion
knee medial rotation when flexed
when hip and knee are flexed (sitting), can extend trunk at hip (to rise)
semitendinosus PA
ischial tuberosity
semitendinosus DA
pes anserine of tibia
semitendinosus nerve innervation
tibial division of sciatic nerve L5, S1, S2
semimembranosus action
hip extension
knee flexion
knee medial rotation when flexed
when hip and knee are flexed (sitting), can extend trunk at hip (to rise)
semimembranosus PA
ischial tuberosity
semimembranosus DA
posterior medial tibial condyle
reflected attachment forms oblique popliteal ligament (to lateral femoral condyle)
semimembranosus nerve innervation
tibial division of sciatic nerve L5, S1, S2
