GLANDS. 407 



COWPER'S GLANDS. 



Cowper's, or the antiprostatic, glands are, as already men- 

 tioned, mucous glands, being the largest examples of this 

 description of gland met with in the human body. 



The description given of these glands by authors in general, 

 their large size and their apparent constitution of lobules, 

 were the reasons which led to their being temporarily classi- 

 fied with the lobular glands. 



The description given of the mucous glands applies in 

 every respect to these. 



A knowledge of their true structure and relationship ex- 

 plains their use, concerning which many vague conjectures 

 have been hazarded. 



LOBULAR GLANDS. 



SALIVARY GLANDS. 



The salivary glands include the parotid, submaxillary, and 

 lingual glands, together with the pancreas. 



These several glands resemble each other very closely in 

 structure, as well as in the characters of the secretions 

 furnished by them. 



The salivary glands consist of lobes and lobules, on the 

 surface of which the blood-vessels ramify ; the lobes are made 

 up of the lobules, and the lobules themselves consist of fol- 

 licles of a rounded or oval form, and each of which is fur- 

 nished with a minute efferent duct, which, uniting with the 

 other ducts of the same size, forms other larger ducts, and 

 these, uniting again with others of still larger calibre, at 

 length form, by their union, the main excretory tube of these 

 organs. (Plate lAV.figs. 1, 2, 3, 4, 5.) 



The follicles contain numerous minute granular cells ; and 

 those of the pancreas, in addition, frequently many shining 

 globules of an oleaginous character.
