Flashcards in test 4 gluteal Deck (36):
1

gluteus maximus origin

Ilium posterior to posterior gluteal line; dorsal surface of sacrum and coccyx; and sacrotuberous ligament

2

gluteus maximus insertion

Most fibers end in iliotibial tract, which inserts into lateral condyle of tibia; some fibers insert on gluteal tuberosity of femur

3

gluteus maximus inervation

Inferior gluteal nerve (L5, S1, S2)

4

gluteus maximus action

Extends thigh and assists in its lateral rotation; steadies thigh and assists in rising from sitting position

5

gluteus medius origin

External surface of ilium between anterior and posterior gluteal lines

6

gluteus medius insertion

Lateral surface of greater trochanter of femur

7

glteus medius innervation

Superior gluteal nerve (L4, L5, S1)

8

gluteus medius action

Abduct and medially rotate thigh; keep pelvis level when opposite leg is raised

9

gluteus minimus origin

External surface of ilium between anterior and inferior gluteal lines

10

gluteus minimus insertion

Anterior surface of greater trochanter of femur

11

gluteus minimus innervation

Superior gluteal nerve (L4, L5, S1)

12

gluteus minimus action

Abduct and medially rotate thigh; keep pelvis level when opposite leg is raised

13

Tensor fasciae latae (tensor of fascia lata origin

Anterior superior iliac spine; anterior part of iliac crest

14

Tensor fasciae latae (tensor of fascia lata) insertion

Iliotibial tract, which attaches to lateral condyle of tibia (Gerdy tubercle

15

Tensor fasciae latae (tensor of fascia lata) innervatin

Superior gluteal nerve (L4, L5, S1)

16

Tensor fasciae latae (tensor of fascia lata) action

Flexes thigh

17

Piriformis (passes through greater sciatic foramen) origin

Anterior surface of 2nd–4th sacral segments; superior margin of greater sciatic notch and sacrotuberous ligament

18

Piriformis (passes through greater sciatic foramen)insertion

Superior border of greater trochanter of femur

19

Piriformis (passes through greater sciatic foramen)innervation

Branches of anterior rami of S1, S2

20

Piriformis (passes through greater sciatic foramen) action

Laterally rotate extended thigh; abduct flexed thigh; steady femoral head in acetabulum (stabilizes hip joint

21

Obturator internus (passes through lesser sciatic foramen) origin

Pelvic surface of ilium and ischium; and obturator membrane

22

Obturator internus (passes through lesser sciatic foramen)insertion

Medial surface of greater trochanter (trochanteric fossa) of femur

23

Obturator internus (passes through lesser sciatic foramen innervation

Nerve to obturator internus (L5, S1

24

Obturator internus (passes through lesser sciatic foramen)action

Laterally rotate extended thigh; abduct flexed thigh; steady femoral head in acetabulum (stabilizes hip joint)

25

gemelli superior origin

ischial spine

26

gemelli superior insertion

Medial surface of greater trochanter (trochanteric fossa) of femur

27

gemelli superior innervation

Nerve to obturator internus (L5, S1)
-same as obturator internus

28

gemelli superior action

Laterally rotate extended thigh; abduct flexed thigh; steady femoral head in acetabulum (stabilizes hip joint

29

gemelli inferior origin

ischial tuberosity

30

gemelli inferior insertion

Medial surface of greater trochanter (trochanteric fossa) of femur

31

gemelli inferior innervation

Nerve to quadratus femoris (L5, S1)
-same as quadratus femoris

32

gemelli inferior action

Laterally rotate extended thigh; abduct flexed thigh; steady femoral head in acetabulum (stabilizes hip joint

33

Quadratus femoris origin

Lateral border of ischial tuberosity

34

Quadratus femorisinsertion

Quadrate tubercle on intertrochanteric crest of femur and area inferior to it

35

Quadratus femoris innervation

Nerve to quadratus femoris (L5, S1)

36

Quadratus femoris action

Laterally rotates thigh; steadies femoral head in acetabulum
