Shoulder bones Flashcards
4 main bones that make up shoulder complex
Humerus, clavicle, scapula, sternum
humerus articulates with what (proximal and distal)
proximal- glenoid fossa
distal- radius and ulna
name of groove between greater and lesser tuberosity of the humerus
-intertubercular sulcus
key landmarks making up the scapula
-coracoid process, provides attachment site for key shoulder muscles
-Acromion (attachment site to clavicle proximal)
-lateral surface of scap articulates with humerus
-glenoid fossa (lateral)
name for distal and proximal glenoid fossa
-proximal, supraglenoid fossa
-distal, infraglenoid tubercle
bony landmarks of scap
-spine of scap
-supraspinous fossa (top)
-infraspinous fossa (below spine of scap)
-acromion
name for most superior part of sternum
manubrium
name for superior border of manubrium
sternal notch, each side articulates with each clavicle
medial and lateral end of clavicle articulates with what
medial-sternum to form sternoclavicular joint
lateral- acromion to form acromioclavicular joints
2 bony landmarks on inferior surface of lateral 1/3 of clavicle
trapezoid line and conoid tubercle
glenohumeral joint formed between what
formed between proximal end of the humerus and glenoid cavity of the scapula
what is the labrum
fibrous cartilage on the outer rim of glenoid fossa
3 main bursae
subacromial, subscapular, subcoracoid
role of scapulothoracic joint
forms the junction where the anterior surface of the scap glides over the posterior aspect of the thoracic cage
4 ST bursae
-infraserratus bursa (x2)
-supraserratus bursa
-trapezoid bursa
