VISCERAL ANATOMY. 



What is the Parovarium ? The Parovarium, or Organ of Rosenmuller, 

 is a group of tubules, situated in the broad ligament, between the ovary and 

 the Fallopian tube, and converging to a large duct, the Duct of Gartner, 

 which ramifies in the broad ligament, and descends along the side of the 

 uterus. It is thought to be a remnant of the Wolffian Body of foetal life. 

 (See "Reproduction," in COMPEND OF PHYSIOLOGY.) 



THE MAMMAE. 



Describe the Mammae. 

 FIG. 95. 



The breasts are two hemispherical eminences, 

 situated one on each latero-anterior aspect of 

 the chest, extending from the sternum to the 

 axilla, and from the 3d rib to the ;th. Each 

 breast contains the Mammary Gland &&& is 

 surmounted by the Nipple, around the base of 

 which is a zone of colored cutaneous tissue, 

 the Areola, pink in virgins, darker in women 

 who have borne children. In the male the 

 mammae are rudimentary organs, but capable 

 of development under special circumstances. 



Describe the Structure of the Mam- 

 mary Gland. It is a compound conglomer- 

 ate gland, composed of 15 or" 20 lobes and 

 their ducts, 1 with a packing of areolar and 

 adipose tissue, and enveloped by a fibrous 

 capsule which forms septa between the lobes. 

 Each lobe is made up of lobules, 2 and these 

 again are formed by the aggregation of the 

 Acini or terminal vesicles, in which the milk 

 is secreted. The 

 Tubuli Lactiferi or Tubuli Galactophori^- are the excretory ducts of the 

 lobes, one for each. They are formed by the junction of the ducts from 

 each lobule, and converge towards the areola, beneath which they form 

 Ampulla or dilatations, and thence, piercing the nipple, open on its sum- 

 mit by separate orifices. 



What is the Circulus Venosus ? An anastomotic venous circle around 

 <he base of the nipple, from which larger veins run outwards and terminate in 

 the axillary and internal mammary veins. 



Name the Arteries of the Mammas. They are derived from the Tho- 

 racic Branches of the axillary, the Intercostals, and the Internal Mammary 

 arteries.
