040 Tin: LYMPHATICS. 



tin- inguinal nervous branches. They enter the deep inguinal glands, after 

 traversing the crural ring, in company with the prepubic artery. 



4. Popliteal (Hands. 



These glands represent a very small mass composed tit' from three to 

 five independent lobules, situated behind the great sciatic nerve :uni 

 trocnemii muscles, between the long vastus and seinitendinous musrl, <. and 

 near the femoro-popliteal artery. 



They receive some of the lymphatics which arise from the environs of 

 the hock, and those coming from the posterior and inferior part (if the 

 gluteal region. Their efferents join the deep inguinal glands, by following 

 the muscular interstices of the thigh. 



5. Iliac Glands. 



Slightly yellow in colour, and of a soft consistence, these glands are 

 five or six in number, and form a group which is situated in the triangular 

 interval comprised between the two branches of the circumflex iliac m 

 They receive the emergent branches of the anterior crural glands, in id H 

 great number of deep lymphatics from the abdominal wall. Their efferent 

 branches, four or five in number, follow the circumflex iliac artery to pass 

 to the sublumbar glands. 



6. Precrural Glands. 



Placed within the anterior border of the fascia lata, on the track of the 

 circumflex iliac artery, these glands form a small elongated mass, eomposed 

 of a dozen lobules lying close to each other. To this group come afferent 

 vessels from the anterior and internal part of the thigh. It giv. 

 three or four large efferent vessels, which ascend the internal face of the 

 muscle of the fascia lata, accompanying the circumflex iliac artery, and 

 entering the abdominal cavity near the angle of the haunch, to join the iliac 

 glands. 



LYMPHATICS OF THE ABDOMINAL VISCERA. 



1. Glands and Lymphatic Vessels of the Rectum and Small Colon. 



The glands in this portion of the intestinal tube are : at first, two or 

 three lobules placed at the base of the tail and on each side of the sphincter 

 ani; in the second place, a very numerous series of small glandular bodies 

 situated along the small curvature of the viscus; thirdly, some rounded 



A, Facial and nasal plexus whose branches pass to the subglossal glands; n, c, 1'arotid 

 lymphatic gland, sending vessels to the pharyuge.il gland; D, K, Large trunks pa.ssinij 

 towards the thorax; F, G, n, Glands receiving the superficial lymphatics of the neck, 

 a portion of those of the limbs, and those of the pectoral parietes; I, Junction <-ftln: 

 jugulars; J, Axillary veins; K, Summit of anterior vena cava ; I,, Thoracic din-t ; 

 M, Lymphatics of spleen N, of stomach O, of large colou 8, of small colon; K. I..K - 

 teals of small intestine all joining to form the two trunks, P, Q, which open directly 

 into the reccptaculum chyli ; T, Trunk which receives the branches of the Mildmubar 

 glands, U, to which the vessels of the internal iliac glands, v, the receptacles of tin; 

 lymphatics of the abdominal parietes, pas-;: \v, IVccniral glands receiving the lymph- 

 atics of the posterior limb, and which jirrive independently in the abdomen; x, Super- 

 ficial inguinal glands into which the lymphatics of the mamma?, external generative 

 organs, some superficial trunks of the posterior limb, etc., pass; z, Deep inguinal 

 glands receiving the superficial lymphatics, /, of the posterior limb.-.
