Anatomy & Physiology: Bones—Radius.
Structure.
- The forearm bone on the thumb side. You can remember this as “Thumbs up for Rad!”
- It is smaller and shorter than the ulna.
- Head: radial head at the proximal end articulates with both the capitulum of the humerus and the radial notch of the ulna.
- (of radius)
- Radial tuberosity.
- Ulnar notch: at the distal end, medial side, articulates with the ulnar head.
- Styloid process: at the distal end, lateral side. Easily palpateable.
- Radius (distal end) also articulates with 3 bones of the wrist: lunate, scaphoid, and triquetrum.
