runs obliquely across the medial head of the Triceps brachii, and descends to the 

 groove between the medial epicondyle and the olecranon, accompanied by the 

 superior ulnar collateral artery. At the elbow, it rests upon the back of the medial 

 epicondyle, and enters the forearm between the two heads of the Flexor carpi 

 ulnaris. In the forearm, it descends along the ulnar side, lying upon the Flexor 

 digitorum profundus; its upper half is covered by the Flexor carpi ulnaris, its lower

half lies on the lateral side of the muscle, covered by the integument and fascia. In 

 the upper third of the forearm, it is separated from the ulnar artery by a consider- 

 able interval, but in the rest of its extent lies close to the medial side of the artery. 

 About 5 cm. above the wrist it ends by dividing into a dorsal and a velar branch. 

 The branches of the ulnar nerve are: articular to the elbow-joint, muscular, 

 palmar cutaneous, dorsal, and volar.
