Veins. 



The subclavian vein, F. sub- 

 davia, receives the veins of the arm 

 and shoulder. These are: 



1. Deep brachial veins, 

 Venae profundae brachii, for the bra- 

 chial artery and its branches, which 

 they accompany on both sides. They 

 arise as palmar digital veins, form 

 the superficial and deep venous 

 arches, then radial and ulnar 

 veins, finally two brachial veins 

 which unite to form the single 

 axillary vein, whose direct con- 

 tinuation is the subclavian vein. 

 2. Superficial brachial veins, 

 Venae subcutaneae brachii, between skin 

 and fascia, which, freely anastomosing 

 with each other, arise from an arch, 

 the Rete venosum manus dor sale. 



a) The cephalic vein com- 

 mences at the dorsum of the thumb, 

 passes along the inner side of the 

 forearm, above the elbow in the Sul- 

 cus bicipitalis externus, then between 

 M. pectoralis major and M. deltoides, and 

 terminates between these muscles in the 

 axillary vein just below the clavicle. 



b) The basilic vein passes 

 along the ulnar side of the forearm, 

 at first usually double, then becoming 

 single, ascends in the Sulcus bicipitalis 

 internus, pierces the fascia in the 

 middle of the upper arm and opens 

 into the internal brachial vein. 



c) The median vein is either 

 single or double, and divides into the 

 median cephalic and the median 

 basilic; the latter is usually the 

 larger. An anastomosing branch 

 for the deep radial or brachial veins 

 is always present.
