LYMPHATICS 



LYMPHATICS OF THE UPPER EXTREMITY. 



The Lymphatic Glands of the Upper Extremity (Fig. 317) may be subdivided 

 into two sets, superficial and deep. 



The superficial lymphatic glands are few, and of small size. There are occa- 

 sionally two or three in front of the elbow, and one or two above the internal 

 condyle of the humerus, near the basilic vein.

The deep lymphatic glands are also few in number. In the forearm ;i 

 small ones are occasionally found in the course of the radial and ulnar vessels; 

 and in the arm, there is a chain of small glands along the inner side of the 

 brachial artery. 



The axillary glands are of large size, and usually ten or twelve in number. 

 A chain of these glands surrounds the axillary vessels imbedded in a quantity 

 of loose areolar tissue ; they receive the lymphatic vessels from the arm ; others 

 arc dispersed in the areolar tissue of the axilla; the remainder are arranged in 

 two series, a small chain running along the lower border of the Pectoralis
