B. Veins of the Superior Extrematies. 
The veins of the upper extremities are superficial and deep. The prin- 
cipal superficial veins are the cephalic, basilic, and median. The superficial 
veins of the hand are principally on the dorsal aspect. On the back of the 
hand there is a venous arch or series of arches, which receive two freely 
anastomosing veins from each finger. From this arch branches ascend, 
two of which being larger and more regular, have received distinct names, 
cephalic and basilic. 
The cephalic ven commences on the outer and back part of the carpus, 
ascends to the bend of the elbow, and continuing along the outer side of 
the biceps, turns forward towards the shoulder, winet sinks deep between the 
pectoral and deltoid muscles to join the axillary vein. 
The baszlic ven commences from the dorsal arch near the lower end of 
the ulna. One branch from the little finger is termed salvatella. Ascend- 
ing along the ulnar side of the forearm, it passes before the internal 
condyle, and continuing up the inner side of the arm, joins the axillary 
vein. 
The median vein arises a little above the wrist, and ascends along the 
middle of the forearm to the bend of the elbow. It here divides into two 
branches ; one (median basilic) joins the basilic vein, the other (median 
cephalic) joins the cephalic vein. 
_ The deep veins accompanying the brachial artery and its branches in’ 
the arm and forearm, two with each inclosed in the same sheath. These 
end in the | 
~ AXILLARY VEIN, which ascends in front of the artery, receives the thoracie 
veins, passes beneath the clavicle, and opposite the lower edge of the first 
rib is named: ~ 
SUBCLAVIAN VEIN. This passes inwards, receiving several veins from 
the shoulder and sides of the neck, as also the jugular veins, and opposite
