Clavicle

sternal (medial) end- articulates with the manubrium of the sternum
acromial (lateral) end- articulates with the acromion of the scapula

2

scapula

spine
acromion- lateral end of spine
glenoid cavity- shallow socket; articulates with head of humerus
coracoid process- beadlike projection
superior border
medial (vertebral) border
lateral (axillary) border
Fossa-shallow depressions

humerus

proximal features
