This series of T2-weighted axial MRIs is from proximal to distal. The first image was taken at the distal forearm. Click here to see the approximate location of this cross-section on a standard radiograph. Remember that connective tissue elements, such as tendons and ligaments will appear black in these images.

Identify the following:

1. radius

2. ulna

3. pronator quadratus

Is this a right or left forearm? (answer) The remaining structures are for your interest only (i.e. you will not be examined on them).

4. radial artery

5. ulnar artery

6. median nerve

7. ulnar nerve

8. flexor carpi radialis tendon

9. flexor carpi ulnaris tendon

10. flexor digitorum superficialis muscle and tendons

11. flexor digitorum profundus muscle and tendons

12. flexor pollicis longus tendon

13. extensor carpi radialis longus tendon

14. extensor carpi radialis brevis tendon

15. extensor digitorum tendons

16. extensor carpi ulnaris tendon
