those from the areola and nipple. Its efferents are collected into two trunks which 

 pas? to the pectoral group of axillary glands. The vessels which drain the medial 

 part of the mamma pierce the thoracic wall and end in the sternal glands, while 

 a vessel has occasionally been seen to emerge from the upper part of the mamma 

 and, piercing the Pectoralis major, terminate in the subclavicular glands (Fig. 607).

 represented by continuous lines, and efferent and internodular vessels by dotted lines. (Cunningham.) 



The deep lymphatic vessels of the thoracic wall (Fig. 621) consist of: 



1. The lymphatics of the muscles which lie on the ribs: most of these end in 



the axillary glands, but some from the Pectoralis major pass to the sternal glands. 



2. The intercostal vessels which drain the Intercostales and parietal pleura. Those 



draining the Intercostales cxterni run backward and, after receiving the vessels
