anteriorly convex
Shape of clavicle in middle
anteriorly concave
Acromial end articulate with what
articular process of scapula
Sternal end of scapula articulates with what
manubrium of sternum
Structure near sternal exremity that runs from clavicle to first rib, hold clavicle in place
costoclavicular ligament
Muscle that binds clavicle to first rib
subclavian mx
bony prominence where conoid ligament attaches
conoid tubercle
trapazoid ligament attaches where
trapezoid line
Ligaments that run from clavicle from coracoid process of scapula
coracoclavicular ligament
coracoclavicular ligament most medial part is called
trapezoid ligament
coracoclavicular ligament most lateral part is called
conoid ligament
Medial border of the scapula is typicall how many cm lateral to vertebral column
5cm
On the face of the lateral angle of the scapula is what
glenoid fossa
Glenoid fossa form what joint with what bone
glenohumeral joint, humerus
Suprascapular notch contains what
suprascapular nerve
Concavity on anterior that houses subscapularis muscle
subscapular fossa
On posterior view, bony prominence near top of scapula
spine of scapula
Surface below spine
infraspinous fossa
Surface above spine
supraspinous fossa
Muscle in infra/supra spinous fossa
infraspinatous, supraspinatous
Mx that attaches at the supraglenoid tubercle
long head of biceps brachii
Mx that attaches to infraglenoid tubercle
long head of triceps brachii
Antomical neck of humerus is what
epiphyseal line
Surgical neck is what
point of humerus most prone to fracture
Name of groove where long head of biceps runs
intertubercular goove
Mx attaching to greater and lesser tubercles of humerus
mx of rotator cuff
deltoid mx attaches where on humerus
deltoid tuberosity
Articulation of clavicle with sternum
sternoclavicular joint
Articulation of clavicle with acromion
acromioclavicular joint
Articulation of glenoid fossa with humerus
glenohumeral joint
Aticulation of scapula with thoracic wall
scapulothoracic joint
Dysfunction at any one of the scapular joints can present as
lack of motion
glenohumeral joint is what type joint
synovial, ball and socket
Articular cartilage in glenohumeral joint is what type of cartilage
hyaline
Fibrous cartilage that rims the glenoid fossa, stabilizes and guides motion of humerus
glenoid labrum
Injury to the glenoid labrum in which biceps tendon pulls superior portion of glenoid labrum, bet 10-2 o’clock region og glenoid labrum
SLAP lesion
Injury to the glenoid labrum at 3-6 o’clock that is a tear of the glenoid labrum
bankart lesion
Capsule that surrounds the entire glenohumeral joint
loose fibrous capsule
Loose fibrous capsule is lines with
synovial membrane
Loose fibrous capsule of the glenohumeral joint forms synovial sheath around
tendon of the long head of the biceps
Tendon of the long head of the biceps attaches to the
supraglenoid tubercle
Three glenohumeral ligaments
Superior, middle, and inferior glenohumeral ligament
Glenohumeral ligament that keep shoulder from dislocating due to downward pull of arm
SGHL
Glenohumeral ligament that keep should from anterior dislocation when arm is abducted to 45-60 deg
MGHL
Glenohumeral ligament, most important, from labrum to humerus, that keeps shoulder from dislocating from anterior and inferior dislocation when arm is in throwing position
IGHL
Shoulder dislocates through what space
space bet SGHL and MGHL

external rotation
Function motion of reaching back behind back fromunder shoulder is what type of rotation on GHJ
internal rotation
Articulation of the manubrium and clavicle, sternal end of clavicle with clavicular notch of manubrium
sternoclavicular joint
