THE DUCTLESS GLANDS. 



are associated with the ganglia of the cardiac and inferior mesenteric plexuses. They 

 have been reported in association with ganglia situated upon the surface of the suprarenal 

 glands, upon the surface and in the sinus of the kidney, in relation to the ureter, the 

 prostate, the epididymis, the ovary, the paroophoron, and the retro-peritoneal Pacinian 

 corpuscles, but have not been discovered in association with the ganglia of the branches 

 of the nervus trigeminus.

(ii.) The Chromaphil Bodies of the Sympathetic Plexuses. From seven tc 

 seventy masses of chromaphil tissue are developed in relation to the abdominal 

 sympathetic plexuses, independently of the ganglia and in addition to the paraganglia, 

 Of these, the most important are the two aortic bodies, which lie one on either side of the 

 aorta in the region of the origin of the inferior mesenteric artery. In the new-bon 

 child they are smooth brownish structures, 8-11 mm. in length, not infrequently united 

 by an isthmus superiorly (Zuckerkandl). They degenerate as life advances, ceasing tc ; 

 be visible soon after puberty, but remaining discoverable, microscopically, until about th< 

 age of forty.
