Q26 Shoulder Girdle

Question 1

Name the bones that comprise the Shoulder girdle

Answer 1

Clavicle and Scapular

Question 2

List the movements of the shoulder girdle

Answer 2

Protraction / Retraction.
Elevation / Depression.
Medial and Lateral rotation of the scapular

Question 3

For Protraction state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 3

Scapular moves horizontally forwards around the thorax, clavicle moves backwards at the SC joint, Serratus Anterior and Pectoralis Minor

Question 4

For Retraction state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 4

Scapular moves horizontally backwards around the thorax, clavicle moves forwards at the SC joint, Rhomboid Major and Minor plus middle fibres of Trapezius

Question 5

For Elevation state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 5

Scapular moves superiorly on the thorax, clavicle moves downwards. Upper fibres of trapezius and Levator Scapulae

Question 6

For Depression state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 6

Scapular moves Inferiorly on the thorax, clavicle moves upwards. Serratus Anterior and Pectoralis Minor plus lower fibres of Trapezius

Question 7

For Medial Rotation state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 7

Inferior angle of the scapular rotates towards the spine, clavicle rotates along its axis, Rhomboids, Pectoralis Minor and Levator Scapulae

Question 8

For Lateral Rotation state the movement of the scapular, direction of movement of the clavicle at the sternoclavicular joint

Answer 8

Inferior angle of the scapular rotates away from the spine around the thorax, clavicle rotates along its axis,Upper and Lower Trapezius and Serratus Anterior

Question 9

State the importance of the shoulder girdle in the range of movement of the upper limb

Answer 9

Allows the arm to be held away from the body enabling the hand to reach 360 degrees around the body
