015. The Superficial 



Lymphatics -of the Upper 



Extremity. 



The lymphatics of the upper ex- 

 tremity, the thorax and shoulder, col- 

 lect in the Plexus lympliaticus axillaris, 

 with 8 12 axillary glands. This 

 plexus forms the Truncus lympliaticus 

 subdavius, which opens into the thora- 

 cic duct of the corresponding side. 



The lymphatics of the 

 upper extremity are partly 

 superficial and partly deep. 



a) The superficial 1 y m- 

 p ha tics commence at the fingers; 

 those from the palmar side ascend 

 on the inner side of the forearm, 

 those from the dorsal side at first 

 on the outer side, then across the 

 border of the ulna to the inner sur- 

 face of the forearm. In the bend 

 of the elbow are one or two Glan- 

 dulae cubitales. The lymphatics pass 

 some directly into the axilla, others 

 with the cephalic vein to the space 

 between M. ddtoides and M. pectoratis 

 major. 



b) The deep lymphatics 

 accompany the veins of the arm, but 

 are less numerous than the superficial ; 

 they form a few cubital glands, 

 Glandulac, culitales, and deep b ra- 

 dii al glands, Glandulac bracliiales 

 profundac.
