Flashcards in OIAN of gluteal region Deck (51):
1

gluteus maximus o

ilium posterior to posterior gluteal line, dorsal surface of sacrum and coccyx, sacrotuberous lig

2

iliotibial tract (inserts into lat condyle of tib and glut tub)

3

glut max n

inferior gluteal n (l5, s1 s2)

4

glut max a

extend thigh, lat rot, steadies thigh and assists in rising from sitting position

5

glut med o

external surface of ilium b/w ant and post glut lines

6

glut med i

lat surface of greater trochanter of femur

7

glut med, min, TFL N

superior gluteal nerve L5

8

glut med, min, tfl a

abduct and medially rotate thigh, keep pelvis level when ipsilateral limb is wieght bearing and unsuported side during its swing phase

tfl also flexes

9

glut min o

external surface of ilium between ant and inf glut lines

10

glut min i

14

piriform i

superior border of greater trochanter of femur

15

piriformi n.

branches of anterior ramiof S1 and s2 nerve to the piriformis

16

actions of priformis, obturator internus, superior and inferior gemelli

laterally rotate and extend thigh, abduct flexed thigh, steady felmoral head in acetabulum

17

pelvic surface of obturator membrane and surrounding bones

18

obt intern i

medial surface of greater trochanter (trochanteric fossa)

19

obt intern n

obturator internus N l5 and S1
