Question 3

where does the distal humerus articulate with the ulna

Answer 3

at trochlea (medial condyle)

Question 4

where does distal humerus articulate with the radius, and significance

Answer 4

at capitulum (lateral condyle), but only in full flexion

Question 5

3 ligaments which contribute to elbow joint stability and allow pronation and supination or radio-ulnar joints

Answer 5

medial (ulnar) collateral ligament, lateral (radial) collateral ligament, annular ligament (part of proximal radio-ulnar joint)

Question 6

2 movements of elbow joint

Answer 6

flexion, extension

Question 7

Answer 7

brachialis, biceps brachii, brachioradialis, assistance from pronator teres; C5,6

Question 8

2 extensors of elbow joint and nerve spinal levels

Answer 8

triceps brachii, anconeus; C6,7

Question 9

define carrying angle, and what this usually is

Answer 9

deviation (abduction) of long axis of radius and ulna from that of humerus in extension (larger in women, but usually 5-15 degrees)

Question 10
