axial somite of development is really c7 that goes to blank
middle finger
arm means blank
shoulder to elbow
post axial means anything beyond blank
c7
pre axial means like these
c6,c5,c4
ue main blood supply
subclavian –> axillary —> upper extremity
two types of veins in upper extremity
deep, superficial
there are blank deep veins per artery
2
most common clavicle fracture moi
foosh
most clavicle fractures occur on blank of clavicle
jxn between middle/lateral third
ac joint is a blank joint
synovial planar
fracture that has one side broken but the other intact
greenstick
joints of shoulder
sc, ac, gh
scapulothoracic is kind of a blank
joint
scapulathoracic joint is involved in blank
scapulohumeral rhythm
scapulohumeral rhythm is at a blank ratio like blank to blank of scapular motion to gh motion
1:2, 60:120 degrees
sc joint is a blank
synovial saddle
about blank degrees of protraction and retraction
30
sc joint has a blank
articular disk
ligaments of sc joint
sc (anterior/posterior), interclavicular, costoclavicular
sc joint is the only joint that attaches blank to blank
ue, axial skeleton
the articular disc of ac joint is blank and blank shaped
incomplete, wedge
ac joint capsule is blank
loose
two ligaments of ac joint
ac, cc
cc conoid fibers are more blank
vertical
cc trapezoid fibers are more blank
horizontal
ac ligament is blank but cc ligament is blank
internal, external
gh joint is a blank joint
synovial ball and socket
gh joint has a blank capsule and a blank
loose, labrum
most gh dislocations are in the blank direction
inferior and anterior
glenoid labrum tears are most common in blank sports and often accompanied by a blank
throwing, popping
long head biceps tendon has direct contact with the blank of the blank joint
capsule, gh
this also has direct contact with gh joint capsule
bursa
gh joint ligaments
gh (3), coracohumeral, transverse humeral, caracoacromial arch
coracoacromial arch is blank and is made by the blank ligament
extrinsic, coracoacromial
anterior axioappendicular muscles
pec major/minor, subclavius, serratus anterior
paralysis of serratus anterior is due to injury to the blank nerve
long thoracic
when arms are flexed and abducted, this nerve is very vulnerable
long thoracic nerve
pec minor action
draws scapula against thoracic wall/slight depression
pec major heads
clavicular, sternocostal
pec minor is innervated by blank cord
medial
pec major gets blank fibers but pec minor gets blank
medial/lateral, medial

deltoid, teres major, rotator cuff
rotator cuff mnemonic
sits
innervation of deltoid
axillary nerve
ac joint is blank
weak
ac joint dislocation is aka
shoulder separation
labrum tear usually occurs in blank part of labrum
anterosuperior
a paralyzed serratus anterior will present with a blank scapula
winged
most commonly torn rotator cuff muscle
supraspinatus
attaches at inferior set of greater humeral tubercle
teres minor
attaches at superior facet of greater tubercle of humerus
suprspinatus
three spaces of shoulder
triangular, triangular interval, quadrangular
things in quadrangular space
posterior circumflex humeral artery, axillary nerve
things in triangular space
deep circumflex scapular artery
things in triangular interval
radial nerve, profunda brachii (deep arm artery)
