33
Q

what is the main action of hip adductor muscles on hip

A

adduction

34

gluteus medius
gluteus minimus
fascia lata
iliotibial tract
tensor fascia lata

36
Q

what muscle is this

A

gluteus minimus

arises wing ilium to front greater trochanter

37
Q

what muscle is this

A

gluteus medius

arises ilium to outer aspect greater troachanter

38
Q

what is the anterior part of gluteus medius also responsible for

A

medial rotation hip

39
Q

what is fascia lata

A

a deep connective tissue that surrounds all muscles of the thigh

40
Q

what is the thickening of the fascia lata called

A

iliotibial tract
extends ilium to tibia
tendon of insetion for gljtueus maximus and tensor fascia lata

41
