25
what would you see in the sheaths and bursae if you suspect shoulder pathology
inflammation and increased fluid quantity degradation and loss of fucntion
26
what are the medial and lateral aspects of the coracoclavicular ligaments called
conoid = medial trapezoid = lateral
27
what is the purpose of bursae
to decrease friction
28
what is the coracoacromial ligament/arch and what does it do
helps brace the humerus superiorly
29
what structure is deep to the coracoacromial ligament/arch
subacromial bursa
30
the 4 rotator cuff muscles are
supraspinatus infraspinatus teres minor subscapularis
31
where do the rotator cuff muscles originate from
originate from the scapula
32
what is the function of the 4 rotator cuff muscles
provide extra stabilisation to the shoulder joint and produce movement of the humerus
33
of the 4 rotator cuff muscles 3 are located posteriorly and one is located anteriorly - which is the anterior one
subscapularis
34
where do the rotator cuff muscles insert on the humerus as well as inserting onto the humerus, the muscles do what with the joint capsule deep to them
subscapularis = lesser tubercle other 3 = greater tubercle blend with the joint capsule deep to them
35
what two muscles are inferior to the infraspinatus from the posterior view
teres minor and major
36
what movement does the supraspinatus muscle cause
abduction (the first 15*)
37
what movement does the infraspinatus muscle cause
external rotation
38
what movement does the teres minor muscle cause
external rotation
39
what movement does the subscapualris muscle cause
internal rotation
40
are muscles active or passive stabilisers of the shoulder joint
active
41
whichbony prominence of the scapula does the supraspinatus muscle pass under
acromion
42
what are the most common directions for the dislocation of the humeral head
inferior and anterior
43
stabilisation is another role of the long tendon of the bicep brachii and what is its specific role in stabilisation
maintains the humeral head in the glenoid fossa and prevents over rotation
44
where does the short tendon of bicep brachii attach to on the scapula
coracoid process
45
what is the main artery from the aorta that supplies the upper limb
subclavian artery
46
what is the name of the subclavian artery once it has passed the lateral border of rib 1
axillary artery
47
at what bony landmark does the subclavian artery become the axillary artery
lateral border of rib 1
48
what does the axillary artery supply
shoulder and armpit regions shoulder joint itself
49
at what muscular landmark does the axillary artery become the brachial artery
inferior border of teres major
50
what is the name of the axillary artery once it has passed the inferior border of teres major
brachial artery
51
what is the main distal tributary of the axillary vein
basilic vein
52
what area does the basilic vein drain from
superficial medial aspect of arm/forearm
53
what smaller deeper veins lead off from the basilic vein and follow the artery more intimately
brachial vein
54
what is the lateral counterpart to the basilic vein
cephalic
55
what area does the cephalic vein drain to
drains into the axillary vein higher in the shoulder
56
what is the order of arteries in the flow of blood from the aorta down to the lower arm
aorta subclavian artery axillary artery brachial artery
57
what is the order of veins in the flow of blood from the lower arm to the aorta
brachial veins -> basilic vein basilic & cephalic veins -> axillary vein axillary vein -> subclavian vein
58
which is lateral and which is medial basilic and cephalic veins
``` lateral = cephalic medial = basilic ```
59
what is the network of major nerves in the shoulder region referred to as
brachial plexus
60
the brachial plexus carries nerve fibres from which vertebral levels
C5-T1
61
what is the structural organization of nerves from the spine to the distal regions
roots -> cords -> terminal nerves
62
what are the 3 cords of the brachial plexus
medial lateral posterior
63
to which anatomy are the 3 cords of the brachial plexus named respective to
axillary artery
64
what are the 5 terminal nerves that are formed from the 3 cords of the brachial plexus
``` median ulnar radial axillary musculocutaneous ```
65
what does the axillary nerve supply
