Question | Answer |
Humerus inserts where? | Glenoid cavity of scapula |
Coracoid what is? | forward process from scapula |
Acromion what is? | backward process that comes off spine of scapula |
clavicle to scapula art via? | Acromion |
Pectoralis Minor O? I? A? | O-2,3,4 ribs I-coracoid process A-depresses shoulder |
Subclavius O? I? A? | O-1st rib I-under clavicle A-steadies clavicles while shoulder moves |
Pectoralis Major O? I? A? | O-1)front medial 1/2 clavicle 2)upper costal cartilages 3)External oblique aponeurosis 4)sternum front I-Greater tubercle of Humerus A-1)adducts arm 2)med rotates arm |
Scapular notch? | upper boder, neurovasc bundle -> back of scapula |
Subscapular bursa between? | joint capsule & muscle |
Subscapularis I? A? | I=Lesser tubercle of H A= 1) adduct 2) med rotator 3)secures head of humerus in glenoid |
Teres major O I A | O=post,lat surface scapula I=below subscapularis L tubercle of humerus A=A= 1) adduct 2) med rotator 3)secures head of humerus in glenoid |
Latissimus Dorsi O I A | O= T and L spinous process, lig, thoracolumbar fascia, illiac crest I=flat tendon -> intertrabecular groove of H A= 1) adduct 2) med rotator 3)great climbing muscle pulls trunk up |
Serratus anterior O I A | O=1-8 ribs I= medial border of scapula A= protracts scpula forwards secures scpula to chest wall if paralysed-> winged scapula |
Deltoid O I A | O=U shaped, lat border clavicle -> acromion -> scapular spine I=deltoid tuberosity of H A= ant fibres - flex post fibres extend med main abductor |
Muscles of back of scapula (3) | 1 Supraspinatus 2 Infraspinatus 3 Teres Minor |
Supraspinatus O I Rel Clnical (2) N Art A | O= spupraspinous fossa -> under acromion I=G. tubercle H Rel=capsule below, subacromial bursa above Clinical=1 tendon rupture injur 2 caification N=suprascapular n Art=subclavian A=initiation + maintain abduct + stability |
Infraspinatus O I N A | O=infraspinous fossa I=G. tubercle of H N=suprascapuar n via glenospinous notch ->infra A=lat rotator stability |
Teres minor O I A N | O=infraspinous fossa I=G.tubercle of H A=lat rotator stability N=axillary n post cord brachial plexus between subscapularis/teres major |
Levator scapulae and Rhomboids O I N A | O=vertebral column I=med edge scapula N=dorsal scapular n A=rotate scpula so that genoid faces down |
Trapezious O I A N | o=along vert column, back of skull -> C/T vertebrae spines I=lat 1/3 clavicle, spine scapula ->acromion A=rotates scapular so glenoid faces up N=CN XI accessory n |
Cavicular joints (2) | sternoclavicular, acromioclavicular, coracoclavicular ligament |
Sternoclavicular joint Type Between Other | T=synovial with articular disk inbetween B=1st rib-manubrium (1 cart immobile) -> med head clavicle O= see-saw movement opp to shoulder pivot = lig c->1st rib |
Coracoclavicular lig use | supports weight of upper limbs |
Acromioclavicular joint T A | T=synovial A=only small gliding move |
labrum glenoidale | rim of fibrous tissue around glenoid to increase art surface deepens |
bursas = def | protrudations of synovial membrane decreases friction bet muscle -joint |
Ligaments of shoulder joint | 1)coracohumeral -> G tubercle prev excessive external rotation 2)coracoacromial prevents excessive upward displacement |
Synovial membrane NB | lines all intracapsular structures except articular cartilage |
subacromial bursa NB | not cont with shoulder joint synovia sep joint from coracoacromial arch/deltoid |
Rotator cuff | tendons of muscles that surround joint Above=Supraspinatus Behind=Infraspinatus + T minnor In front=Subscapularis below=nothing, fold of Sub+Infra dislocation! |
Movement-Adduction | pec major +lat dorsi |
Movement-Abduction | intiated by supraspinatus, maintained by deltoid, if s paralysed swing passively then deltoid >90 = scapular rotates increase art surface |
Movement-flexion | deltoid-ant fibres pec major |
Movement-extension | deltoid post fibres + lat dorsi |
Rotation of humerus | subscapularis, infraspinatus, teres major |
all ab, add, flex, extend =? | circumduction =/ rotation |
shoulder dislocation=>? | test for axillary nerve damage skin over deltoid tuberosity, + deltoid strength |
cervical rib | brachial plexus injury |
Axilla boundaries | front= clavicle back=upper border scapula med=1st rib outer border |
Brachial plexus nerve contributions? | C5-T1 |
Brachial plexus break down and areas | Roots->Trunks->Divisions->Cords behind scalenous anterior->post triangle->under clavicle->axilla |
Long thoracic -> inn | serratus ant |
Dorsal scapular inn | levator scapulae, rhomboids |
subscapular n.s inn | subscapularis t major |
Branches of the axillary artery (7) | -superior thoracic A -Thoracoacromial A -Lateral thoracic -Brachial artery -2 circumflex humeral art -subscapular -> circumflex scapular->back scapular muscles thoracodorsal |
Axillary nodes drainig pattern | Anterior/Pectoral -breast Posterior/subscapular-muscles Lateral group-upper limb all-> central nodes -> apical infraclavicular also -> apical |
Position of breast | side sternum->edge pec major rib 2-6 nipple 4th intercostal space |
blood supply -> breast | internal thoracic thoracic brahces of axillary A |
Lymph drain of breast | internal thoracic nodes axillary infraclavicular |
Spread matastises of breast cancer | other breast - thoracic cavity abdominal cavity - abdo wall |
Suprascapular inn | |
thoracodorsal->inn |
