Origin: Tensor fasciae latae
anterior superior iliac spine and superior part of notch inferior to it
Origin: Sartorius
anterior superior iliac spine and superior part of notch inferior to it
Origin: Rectus Femoris

Main Actions: Tensor Fasciae latae
abducts, medially rotates, and flexes thigh at hip; helps keep knee extended
Main actions: sartorius
flexes, abducts, and laterally rotates thigh at hip joint; flexes knee joint
Main actions: rectus femoris
extends leg at knee joint; rectus femoris also steadies hip joint and helps iliopsoas flex thigh at hip
Main Actions: vastus lateralis
extends leg at knee joint
Main actions: vastus medialis
extends leg at knee joint
Main actions: vastus intermedius
extends leg at knee joint
