APPLIED ANATOMY. 



If the hand is firmly clenched and flexed on the forearm the tendons on the 

 anterior surface of the wrist become prominent. The most evident is the palmaris 

 longus which, though sometimes absent, usually stands out clear and sharp. Lying

along its radial border is the tendon of the flexor carpi radialis; between the two on 

 a lower level lies the median nerve. In front of the ulna, and going directly down- 

 ward to the pisiform bone, is the tendon of flexor carpi ulnaris (Fig. 349).
