Bones of upper limb

1.Arm:humerus

2.Forearm:radius ) is the lateral bone )ulna ( is the medial bone )

3.Hand: carpal bones are 8, metacarpal bones are 5

and phalanges ( 14 )

The humerus: is a long bone ,has a body

(shaft) and two ends (extremities)

The upper proximal) end : head of humerus

lateral greater tubercle

anterior lesser tubercle

surgical neck

Body: deltoid tuberosity

sulcus for radial nerve

The lower end: lateral capitulum

medial trochlea

The radius

The proximal end: a head, neck ..and

tuberosity .

The shaft: interosseous borderThe distal end: styloid process

The wrist joint is made up between radiusand two carpal bones; the ulna does notshare in formation of wrist joint .
