Question 1

The only attachment of the upper extremity to the axial skeleton is via the …..and its attachment through the …… at the……

Answer 1

scapula; clavicle, sternoclavicular joint

Question 2

Which two bones are primary involved in the movement of the shoulder gridle?

Answer 2

scapula and clavicle

Question 3

This joint is not a true synovial joint, due to its not having regular synovial features and to the fact that its movement is totally dependent on the sternoclavicular and acromioclavicular joints

Answer 3

scapualtoracic

Question 4

This joint is classified as an arthrodial joint. It has a 20- to 30-degree total gliding and rotational motion accompanying other shoulder girdle and shoulder joint motions.

Answer 4

acromicalavicular joint

Question 5

This is classified as a (multiaxial) arthrodial joint although there is anatomical justification to classify it as a sellar joint. In relation to the manubrium of the sternum, the clavicle moves anteriorly 15 degrees with protraction and moves posteriorly 15 degreesPage 92 with retraction.

Answer 5

sternoclavicular joint

Question 6

Movement of the scapula laterally away from the spinal column, as in reaching for an object in front of the body

Answer 6

Abduction (protraction)

Question 7

Movement of the scapula medially toward the spinal column, as in pinching the shoulder blades together

Answer 7

adduction (retraction)

Question 8

Upward or superior movement of the scapula, as in shrugging the shoulders

Answer 8

elevation

Question 9

Downward or inferior movement of the scapula, as in returning to a normal position from a shoulder shrug

Answer 9

depression

Question 10

Turning the glenoid fossa upward and moving the inferior angle superiorly and laterally away from the spinal column to assist in raising the arm out to the side

Answer 10

upward rotation

Question 11

Returning the inferior angle medially and inferiorly toward the spinal column and the glenoid fossa to its normal position, as in bringing the arm down to the side. (Once the scapula has returned to its anatomical position, further downward rotation actually results in the superior angle moving slightly superomedial.)

Answer 11

downward rotation

Question 12

true or false:The shoulder joint and shoulder girdle work together in carrying out upper-extremity activities

Answer 12

true

Question 13

Consequential movement during abduction in which the scapula rotates about its vertical axis, resulting in posterior movement of the medial border and anterior movement of the lateral border

Answer 13

lateral tilt

Question 14

Return from lateral tilt; consequential movement during extreme adduction in which the scapula rotates about its vertical axis, resulting in anterior movement of the medial border and posterior movement of the lateral border

Answer 14

medial tilt

Question 15

Consequential rotational movement of the scapula about the frontal axis occurring during hyperextension of the glenohumeral joint, resulting in the superior border moving anteroinferiorly and the inferior angle moving posterosuperiorly

Answer 15

anteiror tilt

Question 16

Consequential rotational movement of the scapula about the frontal axis occurring during hyperflexion of the glenohumeral joint, resulting in the superior border moving posteroinferiorly and the inferior angle moving anterosuperiorly

Answer 16

posterior tilt

Question 17

Scapula is an …… bone.

Answer 17

ireggular

Question 18

Shoulder girdle serves as a ……from which the ……..moves

Answer 18

base; upper extremity moves

Question 19

Scapula provides attachment point of the …..

Answer 19

upper extremity
