VEINS OF THE SUPERIOR EXTREMITY. 



The veins of the superior extremity begin at the 

 extremity of the fingers, and are 

 divided into the superficial and 

 deep. 



The superficial are the cephalic, 

 basilic, and median veins. 



The cephalic is formed on the back 

 of the wrist by the union of the dor- 

 sal veins of the hand. It ascends 

 along the radial side of the fore- 

 arm to the elbow, and thence up- 

 ward along the outer side of the 

 biceps to the groove between the 

 pectoral and deltoid muscles, where 

 it dips down to join the axillary 

 vein just below the clavicle. 



The basilic begins at the lower 

 extremity of the ulna by several 

 branches, one of which from the 

 little finger is called vena salvatella. 

 It ascends along the ulnar side of 

 the forearm to the inner condyle, 

 thence to the inner side of the arm, 

 where it penetrates the fascia, gets 

 in front of the brachial artery, and 

 joins the brachial vein. The basilic 

 often ascends the forearm by two 

 trunks, an anterior and posterior, 

 which unite into one just below the 

 elbow-joint.
