OVARY (NORMAL ANATOMY). 



explained by the much smaller number of 

 blood-vessels that it contains, as compared 

 with the general parenchyma of the ovary. 

 The tunica albuginea, therefore, is not merely 

 a more condensed form of the ovarian stroma, 

 but appears to result from a development of 

 tissues which exist in the stroma in an ele- 

 mentary or embryonic form, as well as from a 

 more close conjunction and blending of those 

 tissues. 



2. The Parenchyma or Stroma,( fig. 371.c,and 

 Jig. 372. 6-) constitutes the proper tissue of the 



549 



ovary. It lies immediately beneath the tunica 

 albuginea, and fills up the whole of the inter- 

 mediate space between the ovisacs, to which 

 it acts as a germ bed, protecting the ova from 

 injury, and serving for the conveyance of blood- 

 vessels to the ovisacs. This tissue is some- 

 times of a pttle-pink, but more often of a 

 bright-red colour, from the large number of 

 blood-vessels which it contains, whose ar- 

 rangement proceeding from within, and radi- 

 ating outwardly in all directions, gives to this 

 tissue, when viewed by the naked eye or by
