Section 1

Question Answer
iliacus muscle origin:-iliac fossa of os coax
iliacus muscle action:-flexes & laterally rotates thigh at hip; flexes trunk & pelvis (if origin & insertion are reversed)
iliacus muscle insertion: -lesser trochanter of femur
psoas major muscle origin:-body and bases of transverse processes of L1-L5
psoas major muscle insertion:-lesser trochanter of femur
psoas major muscle action:-flexes & laterally rotates thigh at hip; flexes vertebral column(torso)
tensor fasciae latae origin:-anterior iliac crest
tensor fasciae latae insertion: -lateral condyle of the tibia via ilitoibial tract
tensor fasciae latae action:-abducts and flexes thigh at hip
adductor magnus muscle origin-oblique head:-inferior ramus
adductor magnus muscle origin-vertical head:-ischial tuberosity
adductor magnus muscle insertion-oblique head:-gluteal tuberosity, linea aspera and proximal supracondylar line of femur
adductor magnus muscle insertion-vertical head:-adductor tubercle of femur
adductor magnus muscle action-oblique head:adducts and flexes thigh at hip
adductor magnus muscle action-vertical head:-extends thigh at hip

Section 2

Question Answer
sartorius muscle origin: -anterior superior iliac spine (ASIS) and the region just below it
sartorius muscle insertion:-proximal tibia, medial to tibial tuberosity(part of pes anserinus)
satorius muscle action: -flexes, abducts, & laterally rotates thigh at hip;(also flexes leg at knee)
rectus femoris origin:-anterior superior iliac spine(ASIS) and ilium above the acetabulum
rectus femoris insertion:-quadriceps tendon to base of patella and onto tibial tuberosity via patellar ligament
rectus femoris action:-flexes thigh at hip; also extends leg at knee
pectineus muscle origin:-pectineal line along superior ramus of pubis
pectineus muscle insertion:-posterior surface of femur, inferior to the lesser trochanter
pectineus muscle action:-adducts and flexes thigh at the hip
adductor longus muscle origin:-superior aspect of pubis, below public tubercle
adductor longus muscle insertion:-middle third of linea aspera of femur along medial lip
adductor longus muscle action:-adduct and flexes thigh at hip(may also laterally or medially rotate the thigh)
adductor brevis muscle origin:-lateral surface of inferior ramus of pubis
adductor brevis muscle insertion:-proximal portion of linea aspera
adductor brevis muscle action:-adducts and flexes thigh at hip(may also laterally or medially rotate the thigh)
gracilis muscle origin:-inferior border of pubic body near symphysis
gracilis muscle insertion:-proximal medial surface of tibia(part of pes anserinus)
gracilis muscle action:-adducts thigh at hip(it also flexes the leg at the knee and medially rotates leg when knee is flexed)
