THE LYMPH GLANDS AND VESSELS OF THE PELVIC LIMB 703 



of the bowel. They receive afferent vessels from the rectum and anus, and their 

 efferent vessels pass chiefly to the internal iliac glands. 



7. The anal lymph glands (Lg. anales) form a small group of three or four on 

 either side of the sphincter ani externus (Figs. 578) . They receive afferents from the 

 anus, perineum, and tail. Their efferents go to the internal iliac glands. 



THE LYMPH GLANDS AND VESSELS OF THE THORACIC LIMB 



1. The axillary lymph glands (Lgg. axillares) (Fig. .590), some ten to twelve in 

 number, are grouped on the medial face of the distal part of the teres major and the 

 tendon of the latissimus dorsi at the angle of junction of the external thoracic and 

 subscapular veins with the brachial (Fig. 566). Their efferents include most of the 

 lymph vessels of the limb, which come directly or as efferents from the cubital glands. 

 They receive also lymph vessels from the thoracic wall. The efferents accompany 

 the brachial blood-vessels and end in the posterior cervical glands and the thoracic 

 and right lymphatic ducts. 



2. The cubital Ijrmph glands (Lg. cubitales), usually eight to ten in number, 

 form a discoid oval group at the medial side of the distal part of the shaft of the 

 humerus (Figs. 566, 590). They lie behind the biceps muscle on the brachial 

 vessels and median nerve, and are covered by the deep fascia and the posterior 

 superficial pectoral muscle. They receive as afferents most of the vessels from the 

 limb below this point. Their efferents pass chiefly to the axillary glands, but in 

 part to the prescapular glands also. 



In quite exceptional cases a lymph gland may be found on the brachial vessels about the mid- 

 dle of the arm. 



A number of superficial lymph vessels ascend with or near the subcutaneous 

 veins (cephalic and accessory cephalic), and join the prescapular and prepectoral 

 glands. Superficial vessels from the chest-wall and shoulder run across the latter 

 to the prescapular glands. The superficial lymphatics of the pectoral region form 

 a plexus which drains into the posterior cervical and prescapular glands by a number 

 of vessels which accompany the cephalic vein. The deep lymph vessels of the pec- 

 toral region run with the external thoracic vein to the axillary glands. 



In one subject the author observed several small glands along the posterior 

 branch of the dorsal artery, under cover of the rhomboideus. 



THE LYMPH GLANDS AND VESSELS OF THE PELVIC LIMB 



1. The prefemoral or subiliac lymph glands (Lgg. prefemorales s. subiliacae) are 

 situated in the fold of the groin on the anterior border of the tensor fasciae lata, 

 about midway between the point of the hip and the patella (Figs. 575, 576, 582). 

 They lie on the course of the posterior branch of the circumflex iliac artery, and 

 number usually about a dozen. They receive superflcial lymph vessels from the 

 hip, thigh, and flank. Their efferent vessels ascend with the posterior circumflex 

 iliac vein, enter the abdomen near the tuber coxas, and join the external iliac lymph 

 glands. 



2. The deep inguinal lymph glands (Lg. inguinales profunda;) form a large 

 group situated in the proximal part of the femoral canal, between the pectineus and 

 sartorius muscles (Figs. 576, 582). The group is elongated and is commonly four 

 or five inches (ca. 10-12 cm.) in length. They cover the femoral vessels and are 

 related superficially to the inguinal ligament. They receive nearly all of the lyinph 

 vessels of the limb below them. Their efferent vessels ascend to the internal iliac 



glands. 



3. The popliteal lymph glands (Lg. poplitese), usually four to six in number,
