3
Q

What connects the scapula and the thoracic cage

A

Muscle

4
Q

What does the muscular connection between the thoracic cage and scapula allow

A

Great mobility of the shoulder girdle

5
Q

What type of bones does the pelvic girdle consist of

A

Two innominate bones

6
Q

Three elements that make up the pelvic bone

A

The ilium, ischium and pubis

7
Q

In children what are the elements of the pubic bone connected by

A

Cartilage

8
Q

At what age do the pubic elements fuse to form the pubic bone

A

16-18

9
Q

What does the pectoral girdle serve as

A

A muscle attachment site for muscles of the upper back, neck and chest

10
Q

The bones of the pelvic girdle are

A

Strongly united

11
Q

Since the bones of the pelvic girdle are strongly united this makes the structure

A

Largely immobile and good for weight bearing

12
Q

What does the pelvic girdle allow in relation to weight bearing

A

It allows for the weight of the torso to be passed into the lower limbs which improves stability

13
Q

Description of the scapula

A

It is flat and triangular which allows for soft muscle attachment

14
Q

Description of the clavicle

A

Serves as a rigid support from which the scapula and upper limb are suspended

15
Q

What is loaded between the superior and lateral borders of the scapula

A

The glenoid fossa

16
Q

What is the glenoid fossa

A

A shallow depression that articulates with the humerus bone of the arm to form the glenohumeral joint.

17
Q

What are the small bony bumps located immediately above and below the glenoid cavity

A

The supraglenoid tubercle and the infraglenoid tubercle

18
Q

What is the function of the supra and infraglenoid tubercles

A

Site of muscle attachment of the arm

19
Q

The cortacoid process is the attachment site for

A

Muscles of the anterior arm and chest

20
Q

Function of the ischium

A

Supports the body while sitting

21
Q

What acts as a sites of muscle attachment for muscles of the thighs

A

Anterior superior and inferior iliac spines

22
Q

What does the ilium articulate with

A

The sacrum

Q

What is the articulation between the ilium and sacrum called

A

Sacroiliac joint

24
Q

What serves as an attachment site of the posterior thigh muscles

A

Ischial tuberosity

25
Q

What stabilises the pectoral girdle

A

The rotator cuff muscles

26
Q

What muscles stabilise the pelvic girdle

A

The gluteus mediums and minimums, piriformis, quadratus femoris and obturator internus

27
Q

A

It is less than 90 degrees in males and greater than 90 degrees in females

30
Q

Differences in the pelvic inlet in males and females

In males it is more heart-shaped, while in females it is more round or oval

31
Q
