Forearm
Consists of radius (thumb side)
and ulna (pinky side)
Connected by interosseous
membrane
 Interosseous membrane is
fibrous connective tissue
Each has nutrient foramina –
openings for nutrients
Ulna
 Olecranon process – at proximal end; forms
the prominence of the elbow
 Trochlear notch – curved area that forms the
elbow joint
 Coronoid process – articulates with the
trochlea of the humerus
 Ulnar tuberosity – point of attachment for
muscles
 Head – at distal end
 Radial notch – where radius butts up against
ulna
 Styloid process of ulna – point of attachment
for wrist muscles
Radius
 Head – articulates with capitulum of the
humerus and radial notch of the ulna
 Neck – inferior to the head
 Radial tuberosity – rough area that is
site of attachment for tendons of bicep
brachii muscle
 Styloid process of radius – site of
attachment for muscles
