CEPHALIC VEIN. 



The Superficial veins of the fore-arm are the 



Fig. 134. 



Anterior ulnar vein, 

 Posterior ulnar vein, 

 Basilic vein, 

 Radial vein, 

 Cephalic vein, 

 Median vein, 

 Median basilic, 

 Median cephalic. 



The Anterior ulnar vein collects 

 the venous blood from the inner 

 border of the hand, and from the 

 vein of the little-finger, vena salva- 

 tella, and ascends the inner side of 

 the fore-arm to the bend of the 

 elbow, where it becomes the basilic 

 vein. 



The Posterior ulnar vein, irregu- 

 lar in size, and frequently absent, 

 commences upon the inner border 

 and posterior aspect of the hand, 

 and ascending the fore-arm termi- 

 nates in front of the inner condyle, 

 in the anterior ulnar vein. 



The Basilic vein (/3a<r/A/xey, royal, 

 or principal) ascends from the com- 

 mon ulnar vein formed by the two 

 preceding, along the inner side of 

 the upper arm, and near its middle 

 pierces the fascia ; it then passes 



upwards to the axilla, and becomes the axillary vein. 



The Radial vein commences in the large vein of the thumb, on the 



outer and posterior aspect of the hand, and ascends along the outer 



border of the fore-arm to the bend of the elbow, where it becomes the 



cephalic vein. 



The CepJialic vein (xnpetXv the head) ascends along the outer side 



* The veins of the fore-arm and bend of the elbow. 1. The radial vein. 2. 

 The cephalic vein. 3. The anterior ulnar vein. 4. The posterior ulnar vein. 

 5. The trunk formed by their union. 6. The basilic vein, piercing the deep 

 fascia at 7. 9 A communicating branch between the deep veins of the fore-arm 

 and the upper part of the median vein. 10. The median cephalic vein. 11. 

 The median basilic. 12. A slight convexity of the deep fascia, formed by the 

 brachial artery. 13. The process of fascia, derived from the tendon of the biceps, 

 and separating the median basilic vein from the brachial artery. 14. The exter- 

 nal cutaneous nerve, piercing the deep fascia, and dividing into two branches, 

 which pass behind the median cephalic vein. 15. The internal cutaneous 

 nerve, dividing into branches, which pass in front of the median basilic vein. 

 16. The intercosto-humeral cutaneous nerve. 17. The spiral cutaneous nerve, 

 a branch of the musculo-spiral.
