Q

What is the ditsal attachmnet for gluteus minimus?

A

anterior surface of greater trochanter of femur

18
Q

What is the nerve to gluteus minimus?

A

superior gluteal nerve

19
Q

What is the action of the gluteus minimus?

A

abducts and medially rotates the hip joint

20
Q

What does the inferior gluteal neurovascular bundle carry?

A

inferior gluteal artery, vein and nerve

21
Q

Where is the inferior gluteal neurovascular bundle carry?

A

deep to gluteus maximus

22
Q

Where is the superior gluteal neurovascular bundle located?

A

deep to gluteus medius

23
Q

What is the proximal attachment for the tensor fasciae latae?

A

ASIS

24
Q

What is the distal attachment for the tensor fasciae latae?

A

iliotibial tract- lateral condyle of tibia (Gerdy tubercle)

25
Q

What is the nervous supply to the tensor fasciae latae?

A

superior gluteal nerve

26
Q

Whst is the action of the tensor fasicae latae?

A

flexes the hip joint; stabilises knee joint

27
Q

What is the iliotibial tract?

A

thickening of the deep fascia of the thigh

28
Q

What are the deep muscles of the gluteal region?

A

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

29
Q

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

A

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
Q

What are the spinal nerve roots of the sciatic nerve?

A

L4-S3

31
Q

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

A

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

32
Q

What are the spinal nerve roots of the pudendal nerve?

A

S2-4

33
Q

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

A

S1-3

34
Q

What are the 2 main branches of the sciatic nerve?

A

tibial nerve and the common fibular nerve

35
Q

What are the 4 curvatures of the spine?

A

cervical lordosis; thoracic kyphosis; lumbar lordosis; sacral kyphosis

36
Q

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

A

sacrotuberous ligamnet

37
Q

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

A

transversely between them

38
Q

What does the sacrotuberous ligmanet run between?

A

sacrum and ischial tuberosity

39
Q

What does the sacrospinous ligament?

A

between the sacrum and the ischial spine

40
Q

How does the pudendal nerve travel through the gluteal region?

A

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