18
Q

What happens to the capsular ligaments when standing erect?

A

All three ligaments are under moderate tension

19
Q

What occurs to the capsular ligaments upon flexing the hip?

A

They all become relaxed

20
Q

Which ligament is under the greatest tension during hip extension?

A

The inferior band of the iliofemoral ligament

21
Q

What movement is the inferior band of the iliofemoral ligament responsible for?

A

Posterior tilt of the pelvis

22
Q

During adduction of the hip, which band of the iliofemoral ligament becomes taut?

A

The superior band

23
Q

What happens to the pubofemoral and ischiofemoral ligaments during hip adduction?

A

They slacken

24
Q

What occurs to the ligaments during abduction of the hip?

A

The opposite of adduction occurs

25
Q

Fill in the blank: During hip flexion, all three capsular ligaments become _______.

A

relaxed

26
Q

True or False: All capsular ligaments are taut during hip extension.

A

True

27
Q

What is the function of the transverse ligament of the acetabulum?

A

It completes the inferior part of the acetabular rim, creating a foramen with the acetabular notch for vessels and nerves to enter the joint.

28
Q

What type of tissue composes the transverse ligament of the acetabulum?

A

Strong bands of fibrous tissue.

29
Q

Where is the superficial edge of the transverse ligament of the acetabulum located?

A

Flush with the acetabular rim.

30
Q

What structure deepens the acetabulum?

A

The fibrocartilaginous acetabular labrum.

31
Q

How is the acetabular labrum attached?

A

Attached to the bony rim and to the transverse ligament.

32
Q

True or False: The acetabular labrum extends further laterally than the femoral head.

A

True.

33
Q

What is the ligamentum teres?

A

A weak, flattened band of connective tissue within the hip joint

Also known as the ligament of the head of the femur.

34
Q

Where is the ligamentum teres attached?

A

To the acetabular notch and the lower border of the transverse ligament

It narrows as it passes to insert into the fovea capitis on the head of the femur.

35
Q

What type of membrane encloses the ligamentum teres?

A

Synovial membrane

This makes the ligamentum teres intracapsular.

36
Q

Where does the ligamentum teres lie in relation to the femoral head?

A

In the acetabular fossa below the femoral head

37
Q

Is the ligamentum teres important for strengthening the hip joint?

A

No, it is variable in size and occasionally absent

Its importance in strengthening the hip joint is considered minimal.

38
Q

What is the function of the ligamentum teres in adults?

A

Uncertain

39
Q

What is the function of the synovial membrane?

A

Lines the internal surface of the fibrous capsule and covers the acetabular labrum.

40
Q

Where is the synovial membrane attached at the acetabular notch?

A

Attached to the medial margin of the transverse ligament.

41
Q

What does the synovial membrane cover in the acetabular fossa?

A

Almost completely covering the fatty tissue.

42
Q

How does the synovial membrane interact with the ligament of the head of the femur?

A

Extends like a sleeve around the ligament.

43
Q

Where does the synovial membrane attach in relation to the fovea capitis?

A

Attaching to the margins of the fovea capitis.
