THE LYMPHATICS 185 



fourteen inches long, and it extends downwards on the deep face of the 

 mastoido-humeralis towards the attachment of the sterno-maxillaris. 

 The afferent vessels of these glands drain the lymph from the neck, 

 breast, and shoulder. 



The lymphatic vessels from the brachial region open directly into 

 the superior group of brachial glands. 



The efferent vessels of these glands, together with those which drain 

 the axilla and also the capacious though short, efferent vessels from the 

 prescapular glands, open into the prepectoral glands which are placed on 

 the deep face of the scalenus njuscle close to the jugular confluent.
