it has double curve or depression called?
supra and clavicular fossa
long slender bone resembling somewhat an old fashion key
clavicle/ collar bone
inner or sternal end articulate with the sternum forming?

head of humerus
obliquely directed part adjacent to the head
anatomical neck
lateral border just below the anatomical neck
greater tubercle/ tuberculum majus
small bony prominence front of the upper humerus just. below anatomical neck
lesser tubercle/ tuberculum minor
constricted part of the upper humerus below the tubercles
surgical neck
long rounded-part that becomes flattened from front to back as it approaches the elbow
shaft/body/diaphysis
anterior surface above the midpoint of the humerus into which the deltoid muscle
insert
deltoid tubercle/ deltoid tuberosity
distal end of the humerus that articulate with the semi-lunar notch of the ulna
