4

What marks the lateral extent of the gluteal region?

greater trochanter of the femur

5

What are the 4 superficial muscles of the gluteal region?

gluteus maximus; gluteas minimus and gluteus medius and the tensor fasciae latae

6

What are the proximal attachments for gluteus maximus?

iliac crest; sacrum; sacrotuberous ligament and coccyx

7

What is the distal attachment for the gluteus maximus?

iliotibial tract

8

What is the function of the gluteus maximus?

extends the hip joint; stabilises knee joint

9

What is the nerve supply to the gluteus maximus?

inferior gluteal nerve

10

What is the proximal attachment for gluteus medius?

posterior surface of the ilium

11

What is the distal attachment for gluteus medius?

lateral surface of the greater trochanter of femur

12

What is the nerve supply to gluteus medius?

superior gluteal nerve

13

What spinal levels is the inferior gluteal nerve derived from?

L5, S1, S2

14

What spinal levels is the superior gluteal nerve derived from?

L4, L5, S1

15

What is the action of the gluteus medius?

abduct and medially rotate the thigh at the hip joipnt

16

What is the proximal attachment for the gluteus minimus?

posterior surface of ilium

17

What is the ditsal attachmnet for gluteus minimus?

anterior surface of greater trochanter of femur

18

What is the nerve to gluteus minimus?

superior gluteal nerve

19

What is the action of the gluteus minimus?

abducts and medially rotates the hip joint

20

What does the inferior gluteal neurovascular bundle carry?

inferior gluteal artery, vein and nerve

21

Where is the inferior gluteal neurovascular bundle carry?

deep to gluteus maximus

22

Where is the superior gluteal neurovascular bundle located?

deep to gluteus medius

23

What is the proximal attachment for the tensor fasciae latae?

ASIS

24

What is the distal attachment for the tensor fasciae latae?

iliotibial tract- lateral condyle of tibia (Gerdy tubercle)

25

What is the nervous supply to the tensor fasciae latae?

superior gluteal nerve

26

Whst is the action of the tensor fasicae latae?

flexes the hip joint; stabilises knee joint

27

What is the iliotibial tract?

thickening of the deep fascia of the thigh

28

What are the deep muscles of the gluteal region?

piriformis; obturator internus; gemelli-superio and inferior; quadratus femoris

29

What are the actions of the deep muscle layer of the gluteal region?

lateral rotation of the lower limb at the hip joint and also play a role in stabilising the head of femur in the acetabulum

30

What are the spinal nerve roots of the sciatic nerve?

L4-S3

31

Where does the sciatic nerve run through the gluteal region to the posterior thigh?

inferolaterally underneath gluteus maximus, midway between ischial tuberosity and greater trochanter

32

What are the spinal nerve roots of the pudendal nerve?

S2-4

33

What are the spinal nerve roots for the posterior cutanoeous nerve of thigh?

S1-3

34

What are the 2 main branches of the sciatic nerve?

tibial nerve and the common fibular nerve

35

What are the 4 curvatures of the spine?

cervical lordosis; thoracic kyphosis; lumbar lordosis; sacral kyphosis

36

What is the deep surface of the gluteus maximus tethered to?

sacrotuberous ligamnet

37

Where does piriformis run in relation ot the superior and inferior gluteal NVBs?

transversely between them

38

What does the sacrotuberous ligmanet run between?

sacrum and ischial tuberosity

39

What does the sacrospinous ligament?

between the sacrum and the ischial spine

40

How does the pudendal nerve travel through the gluteal region?

exits pelvis superior to the sacrospinous ligamnet before turning anteriomedially to enter the perinuem inferior to the ligament
