<h2>The rotational motion of the forearm</h2>
Explanation:
- The two large bones of the forearm, one being the Ulna and the other is radial bone or radius.
- The Radius is larger in size than the Ulna.
- Radius is prism shaped, little curved longitudinally long bone.
- The part of two joints known as elbow and wrist comprised the Radius.
- Radius link with the capitulum of the humerus at the elbow region.
- Radius forms a joint at the wrist region with the ulna bone.
