Hip and Knee

Muscle	Origin	Insertion	Action
Sartorius	anterior, superior, iliac spine (ASIS)	anterior, medial surface of tibia below condyle	flexes, laterally rotates and abducts thigh
Gracilis	anterior part of lower half of symphysis pubis	anterior medial surface of tibia below condyle	adducts and medially rotates thigh
Biceps Femoris	--	--	--
long head	ischial tuberosity	lateral side of fibula; lateral condly eof tibia	flexion, lateral rotation of leg at knee; extends, adducts and laterally rotates thigh at hip
short head	lateral part of femur	--	--
Semitendinosus (medial hamstring)	ischial tuberosity	anterior, medial surface of tibia below condyle	flexes, medially rotates leg at knee; extends, adducts, medially rotates thigh at hip
Semimembranosus (medial hamstring)	upper, lateral part of ischial tuberosity	posterior part of medial condyle of tibia	flexes, medially rotates leg at knee; extends, adducts, medially rotates thigh at hip
Rectus Femoris	--	--	--
straight head	anterior, inferior iliac spine (ASIS)	upper part of patella, tibial tuberosity	extension of leg at knee; flexion of thigh at hip
reflected head	acetabulum	--	--
Vastus lateralis	anterior and lower borders of greater trochanter	lateral border of patella	extends leg at knee; draws patella laterally
Vastus medialis	?	medial border of patella	extends leg at knee; draws patella medially
Vastus intermedius	proximal two thirds of anterior, lateral part of femur	superior border of patella	extends leg at knee
Popliteus	lateral condyle of femur	posterior surface of tibia	rotates tibia medially on femur or rotates femur laterally on tibia depending on which is fixed
