ses with the radial vein. The ulnar vein, in the region of the elbow- 

 joint, receives a large lateral branch which extends around the end 

 tendon of the biceps and anastomoses above with the vena basilica. 



The vena basilica or cutanea ulnaris is a long vein which originates 

 from the subcutaneous dorsal surface of the index-finger. Near the 

 base of the hand it receives an anastomosing branch from the vena 

 radialis and the vena ulnaris, and then passes upward along the 

 posterior rim of the ulna. It receives numerous branches from the 

 roots of the flight feathers. It crosses below the elbow-joint and 

 reaches the volar surface of the arm. It receives a large branch 

 from the ulnar vein, and then, passing in a diagonal and median 

 direction to the triceps, extends to the shoulder cavity where it 

 empties into the axillary vein. 



. The outer breast veins unite forming a trunk which crosses ven- 

 tral! y to the subclavian artery, and empties into the subclavian 

 vein. 



The vena cutanea abdomino-pectoralis collects the blood from a 

 large skin area of the abdomen, the upper thigh, the breast, and the 

 intercostal region. In the skin of the abdomen it forms a network.

The main trunk passes in the median abdominal line forward and 

 then upward, along the outer edge of the pectoralis major, over the 

 first sternal rib; receives blood from the infrascapular vein, and emp- 

 ties into the pectoralis externa. 



The vena brachialis is located in the middle of the humerus and
