THE LYMPH GLANDS OF THE INFEKIOK EXTEEMITY. 1013 



THE LYMPH VESSELS OF THE THORAX. 



The lymph vessels of the thorax form two main groups (a) the vessels of the thoracic wall, 

 and (6) the vessels of the contents of the thorax. 



(a) The Lymph Vessels of the Thoracic Wall are the intercostal lymph vessels and the 

 lymph vessels of the diaphragm. 



(1) The Intercostal Lymph Vessels receive lymph from the ribs and from the content of the 

 intercostal spaces, and they terminate in the intercostal and sternal glands. Communications 

 are said to exist between the intercostal vessels and the glands of the axilla. 



(2) The Lymph Vessels of the Diaphragm. The lymph vessels from the anterior part of the 

 diaphragm pass to the lower sternal and anterior mediastinal glands, and those from the posterior 

 part to the posterior mediastinal glands. 



(6) The Lymph Vessels of the Contents of the Thorax are : 



(1) The Lymph Vessels of the Heart, which follow the courses of the coronary arteries, and 

 pass to the anterior mediastinal glands. 



(2) The Lymph Vessels of the Pericardium, which terminate in adjacent glands. 



(3) The Lymph Vessels of the Thymus, some of which pass to the anterior mediastinal glands, 

 some to the tracheo-bronchial glands, others to the medial inferior deep cervical glands. 



(4) The Lymph Vessels of the Thoracic Part of the (Esophagus, which are separable into 

 upper and lower groups. The upper pass to the bronchial, the posterior mediastinal, and the 

 lower deep cervical glands. The lower group end in the glands situated at the cardiac end of 

 the stomach. The two groups anastomose together. 



(5) The Lymph Vessels of the Pleura. The vessels from 

 the apical parts of the parietal portion of the pleura pass to the 

 adjacent lymph trunks or their tributaries. The vessels from 



the posterior part of the parietal pleura join the intercostal yCJ^X^J^feo'^- -j Proximal 

 glands, and those from the anterior part end in the sternal jL-^-^jfe^l l'!l U nS l o C i ial in,V?" 

 glands. 



The Lymph Vessels of the Lungs and the Visceral Pleura 

 pass to the broncho-pulmonary glands.

THE LYMPH GLANDS OF THE 

 INFERIOE EXTEEMITY. 



The lymph glands of the inferior extremity, like 

 those of the superior, are separable into a superficial 

 and a deep group. 



The Superficial Lymph Glands lie, almost 

 entirely, in the subinguinal region, though occasion- 

 ally one or more may be situated above the level of 

 the inguinal ligament, and therefore in the inguinal 

 region. On this account they are separated in the 

 >.N.A. into inguinal and subinguinal groups. Both 

 groups lie in the superficial fascia. 



Lymphoglandulse Inguinales. The inguinal 

 lymph glands, when they exist, are merely scattered 

 members of the subinguinal group which lie above the 

 level of the inguinal ligament. They receive afferents 

 from the lower and anterior part of the abdominal 

 wall. Their efferents terminate either in the super- 

 ficial or the deep subinguinal glands. 



Lymphoglandulae Subinguinales Superficiales. 

 -The superficial subinguinal glands (Figs. 811, 817) 

 form two groups, a proximal and a distal, each of 

 which is separable into medial and lateral parts ; but 

 the various members of the groups are intimately 

 connected together by communicating vessels. 



The proximal group lies along the line of the 



inguinal ligament. It may extend from the anterior FIG. 811. DIAGRAM OF THE LYMPH 

 superior spine of the ilium to the pubic tubercle. Its VESSELS AND LYMPH GLANDS OP 

 lateral members receive afferents from the lower and THE LowER ExTREMITY ' 

 lateral part of the abdominal wall, from the buttock, and the proximal and lateral 

 part of the thigh.
