1

What does the pelvic girdle connects?

- vertebral column to the femurs

2

How is the pelvic girdle different to the shoulder girdle?

- much stronger and less flexible

3

How many bones are there in the pelvic girdle and what are there?

3 bones

-left hip bone
- right hip bone
- sacrum

4

How many joints are there in the pelvic girdle and what are they?

- 2 sacroiliac joints
- pubic symphysis joint

5

What is the role of the pelvic girdle?

- strong and stable
- supports weight of the body
- protects organs and blood vessels

6

What is the real life position of the pelvic girdle (how is it positioned in the body)?

- it is slightly tipped forwards
- like a bowl tipped forwards

7

What is another word for the hip bone?

the innominate bone

8

What are the three sections the innominate bone/hip bone is divided into?

1. ilium
2. ischium
3. pubis

9

How do the ilium, ischium and pubic parts of the bone develop?

separately

10

What is the name of the area where the ilium, ischium and pubis fuse?

Acetabulum

11

What is the acetabulum?

the socket that articulates with the femoral head - forming the hip joint (holds the head of the femur)

12

What is the ilium made up of?

Ala and body

13

Where is the triradiate cartilage?

made up of 3 cartilages and is in the acetabulum.

14

What type of joint is the hip joint? (2)

1.ball and socket joint

2.synovial joint

15

Where is the hip joint?

between the head of the femur and the acetabulum of the innominate bone

16

How is stability provided by the hip joint? (3)

1. Acetabular anatomy
2. Fibrous capsule
3. Ligaments

17

What are the ligaments of the hip joint? (3)

1. Ileofemoral
2. Pubofemoral
3. Ischiofemoral

18

What is the articular surface of the acetabulum like?

- smooth
- crescent shaped - lunate surface

19

What is the inferior deficiency of the acetabulum called?

Acetabular notch

20

What is the ace tabular notch bridged by?

transverse acetabular ligament

21

What is the acetabular labrum and what is it's role?

-a rim/lip of cartilage
- role - deepens the articular surface

22

What is the fibrous capsule like?


- strong and dense

23

What aspect of the fibrous capsule enables the hip joint to move around?

- the fact that it is loose and strong

24

What does the proximal attachment of the fibrous capsule encircle?

the rim of the acetabulum

25

Where is the distal attachment of the fibrous capsule?

- femoral neck
- intertrochanteric line
- greater trochanter

26

How does the iliofemoral ligament cover the hip joint?

superiorly and inferiorly

27

What is the strongest ligament of the hip joint?

illiofemoral ligamnet

28

What is the role of the illiofemoral ligament?

- prevents hyperextension of the hip during standing
- as it screws into the femoral head

29

How does the pubofemoral ligament cover the hip joint?

-inferiorly and anteriorly

30

What shape is the illiofemoral ligament?

Y shaped ligament
