342 ELEMENTS OF HISTOLOGY. [Chap. XLIII. 



numerous plexuses of veins are met with. In. tbe 

 centre of the suprarenal body lie the large efferent 

 venous trunks. In the capsule (Kolliker, Arnold), 

 and in the connective tissue around the central veins, 

 are plexuses of lymphatic tubes with valves. The 

 nerves are very numerous, and composed of non- 

 medullated fibres ; in the medulla they form rich 

 plexuses. In connection with these and with those of 

 the outer capsule are small ganglia (Holm, Eberth). 



505. IV. The glandula coecygea and iii- 

 tercarotica. The first of these is a minute corpuscle 

 situated in front of the apex of the os coccygis, and 

 was discovered by Luschka. The gland ula carotica 

 of Luschka (ganglion intercaroticum) is of exactly the 

 same structure as the glandula coccygea. 



506. Its framework is of about the same nature as 

 that of other glands a fibrous capsule and inner 

 fibrous septa and trabeculse. The septa and trabeculre 

 contain in some places bundles of non-striped muscular 

 tissue (Sertoli). 



507. The spaces of the framework are occupied by 

 the parenchyma. This consists of spherical or cylin- 

 drical masses of cells connected into networks. The 

 individual cells are polyhedral epithelial cells, each 

 with a spherical nucleus. According to Luschka, in 

 the new-born child they are ciliated. In the centre 

 of each of the cell-masses lies a capillary blood-vessel, 

 much convoluted and wavy. 



Numerous non-niedullated nerve-fibres forming a 

 plexus are situated in the framework of the gland.
