pelvis and legs

powerful thigh extensor, antagonist of iliopsoas; laterally rotates & abducts thigh; extends and laterally rotates hip

abducts & medially rotates thigh; stedies pelvis during walking

abducts & medially rotates thigh; steadies pelvis

Function: flex trunk on thigh; flex thigh; lateral flexion of vertebral column (psoas)

Function: flexes, abducts, and laterally rotates thigh; flexes knee

Function: flexes, abducts, and medially roates thigh; steadies trunk

Function: adduct & medially rotate & flex thigh

adducts thigh; flexes & medially rotates leg, especially during walking

Function: extends thigh; laterally rotates leg; flexes knee

extends thigh; flexes knee, medially rotates leg

adducts, flexes, & medially rotates thigh

extends knee & flexes thigh at hip

Function: extends knee

Function: extends & stabilizes knee

Function: extends knee; stabilizes patella

Function: flexes, abducts, and laterally rotates thigh; flexes knee

Function: prime mover of toe extension; dorsiflexes foot

Function: extends great toe; dorsiflexes foot

Function: flexes toes, planter flexes and inverts foot

Function: flexes great toe; plantar flexes & inverts foot, push off muscle during walking

Function: plantar flexes & everts foot; helps keep foot flat on ground

Function: flexes & rotates leg medially to unlock extended knee when knee flexion begins

Function: prime mover of dorsiflexion; inverts foot; supports longitudinal arch of foot

Function: prime mover of foot inversion; plantar flexes foot; stabilizes longitudinal arch of foot

plantar flexion; important muscle for locomotion

plantar flexes foot when knee is extended; crosses knee joint; can flex knee when foot is dorsiflexed

Function: helps with sex

Function: controls urine flow and contracts during orgasm (aids in urinary control & childbirth)

helps to support pelvic viscera and resist increases in intra-abdominal pressure

Function: forms the pelvic diaphragm

Function: flexes and rotates thigh medially and flexes vertebral column

Function: lateral rotators of the hip (laterally rotates the extended thigh & abducts flexed thigh)

Function: extends knee and flexes hip

Function: plantar flexes foot
