-KCTIOX OF FROST OF FOREAKM. 



[ the human*. The .pace should be catefully cleaned, so as 



to display the brachial 

 and forearm vessels, the 

 median nerve and 

 branches, the musculo - 

 spiral nerve, and the re- 

 current radial and ulnar 

 arteries. 



In the lower half of 

 the forearm a large artery, 

 radial, is to be laid bare 

 along the outer side of 

 the tendon of the flexor 

 carpi radialis ; and at the 

 inner side, close to the 

 annular ligament, the 

 trunk of the ulnar artery 

 will be recognised as it 

 superficial. These 

 Is and their branches 

 .-hould be carefully 

 .leaned ; and the adjoining 

 muscles may be fixed with 

 -t itches to prevent their 

 displacement. 



The anterior annular 

 ligament of the wrist, 

 which arches over the 

 tendons passing to the 

 hand, is next to be de- 

 fined. This strong band 

 is at some depth from 

 the surface ; and while 

 the student removes the 

 fibrous tissue superficial 

 to it, he must take care 

 of the small branches of 

 the median and ulnar 

 nerves to the palm of 

 the hand. The ulnar 

 - and nerve (covered 

 by an expansion connected 

 with the tendon of the

flexor carpi ulnaris internal 

 to the pisiform bone) pass 

 over the ligament, and 

 will serve as a guide to 

 its depth.
