Question 17

Bones of the hand

Answer 17

Distal, middle and proximal phalanx

Question 18

Name the middle bone of the 3rd digit

Answer 18

Middle phalanx

Question 19

Name a carpal bone that articulates with the 1st metacarpal

Answer 19

Trapezium

Question 20

Is the ulna medial or lateral to the radius

Answer 20

Ulna is medial to the radius

Question 21

Name the articular process of the distal humerus

Answer 21

Capitulum (lateral humerus)

Trachea (medial humerus)

Question 22

Demonstrate and describe possible arm positions for a lateral projection of the scapula, and identify the anatomy visualized on each

Answer 22

Positioning the arm behind the back gives a superior view of the acromion and coracoid processes but sometimes results in superimposition of the humerus over the body of the scapula.
Positioning the arm overhead provides an unobstructed view of the body, but the humeral head superimposes the superior structures of the scapula.
Positioning the arm across the chest also compromises visualization of the superior structures but is often the only position attainable by the patient with a scapular injury.
