A

deltoid

capsule

23
Q

the RCL provides resistance to ____ forces

A

varus

24
Q

annular ligament purpose

A

protect radial head

25
Q

in order to palpate the subacromial/subdeltoid bursa, what motion should be done

A

extend the humerus

26
Q

how can the axillary artery be injured

A

compressed against the humerus (crutches)

27
Q

what ligament acts as a retinaculum for long biceps tendon

A

transverse humeral ligament

28
Q

is there more mobility or stability in the GH joint

A

lots more mobility than stability

29
Q

what may happen if static stability of the GH joint is compromised

A

rotator cuff muscles fire and can cause subacromial impingement

30
Q

do the rotator cuff muscles insert into the joint capsule

yes

31
Q

serratus anterior:

action
nerve roots
innervation

A

A: protraction, upward rotation

NR: C5-C7

innervation: long thoracic nerve

32
Q

when is the annular ligament most taut

A

the extremes or pronation and supination

33
Q

what happens to the position of the elbow in extension

A

the ulna pronates slightly in extension

34
Q

upper trapezius myotome AND innervation

A

C4

spinal accessory

35
Q

articulation of humeroulnar joint

A

distal end of humerus (trochlea)

with proximal end of ulna

36
Q

during shoulder elevation, what direction does the head of the humerus move

A

inferiorly

37
Q

for 180 degrees of elevation, where does the first 30-60 degrees come from

A

GH

38
Q

where is the elbow capsule thin

A

anterior and posterior

39
Q

what does the quadrate ligament do

A

reinforces inferior joint capsule

40
Q

when is sternoclavicular joint injured

A

following injury to AC joint and clavicle

41
Q

where can the axillary artery be palpated

A

lateral wall of the inerior part of the scapula

42
Q

purpose of coracohumeral ligament

A

reinforce biceps tendon

reinforce superior capsule

prevent caudal (downward) dislocation of humerus

43
Q

what type of cartilage is associated with the sternoclavicular joint

A

fibrocartilage

44

out of 180 degrees of elevation, where does 120 degrees of movement come from

A

GH

Q

pec major/pec minor nerve roots AND innervation

A

C5-T1

medial/lateral pectoral nerves

48
Q

purpose of coracoclavicular ligament
