5. Parts of the Radius Radial notch
directly beneath the capitulum of the humerus
Unable to abduct and adduct because of the annular ligament that encircles the radial head and binds it to the radial notch of the ulna

6. Proximal and Distal Radioulnar Joints
Movement – Pronation and Supination

7. Proximal Radioulnar Joint
The two joints of the elbow as well as the proximal radioulnar joint is completely enveloped in a single extensive capsule
The capsule is strengthened by four ligaments
anterior, posterior, radial collateral, and ulnar collateral.
