DUCTLESS GLANDS. 



containing blood-vessels, leucocytes, and large special (splenic) 

 cells. [1213] 



Suprarenal Capsules. These are small and flattened. The 

 right capsule is triangular and rests on the antero-internal 

 aspect of the upper end of the right kidney. Its anterior sur- 

 face looks forward and outward and presents two impressions ; 

 one (for the vena cava) is a narrow strip along the anterior 

 border, which presents a short fissure (hilus) near its upper end; 

 the other, the rest of the surface, is for the back of the right 

 lobe of the liver. Its posterior surface is divided by a curved 

 ridge into an upper flat part which rests on the diaphragm 

 over the spine, and a concave lower part which rests on the kid- 

 ney. Peritoneum covers only a small and variable part of the 

 lower part of the anterior surface . [1213] 



The left capsule is semilunar, usually slightly larger, and 

 rests on the inner border of the kidney just above the hilus. 

 Its anterior surface lies behind the stomach and (lower por- 

 tion) pancreas and splenic vessels ; near its lower end is a slit 

 (hilus) ; peritoneum covers only the gastric area. Its posterior 

 surface is divided by a curved ridge into an upper flat area 

 resting on the left crus of the diaphragm ; and a lower concave 

 area resting on the kidney . [1214] 



Structure. It has a thin connective-tissue capsule from 

 whose inner surface processes run inward to form a framework. 

 The outer cortical portion of the gland forms the chief bulk 

 and is firm and yellowish, the inner medullary part is soft and 

 dark brown. [1215] 



Coccygeal Body. This is a small body lying in front of the 

 tip of the coccyx. It is composed of nodular masses of 

 epithelial-like cells, separated from each other by connective- 

 tissue strands. [1221]
