1. Forearm

2. 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

3. 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

4. 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
