 Sex, Male. 



High, origin of ulnar artery (left). 



This artery arises from the front of the brachial artery at the 

 same level as the superior profunda artery. In the arm it lies super- 

 ficially along the line of the brachial artery. In front of the elbow- 

 joint it passes under the bicipital fascia and in the forearm lies 

 superficial to the flexor muscles, immediately beneath the deep fascia. 

 It passes under the anterior annular ligament of the wrist and forms 

 a normal superficial palmar arch. 



Branches. In the arm a muscular branch is given off to the 

 biceps muscle and muscular branches are given off to the flexor 

 muscles of the forearm. No ulnar recurrent artery is given off. The 

 arteries of the right upper extremity are normal. 



In the left upper extremity no palmaris longus muscle exists.
