100 s FEMALE ORGANS OF GENERATION. 



Ovary. Rabbit, for corpus luteum. (p. 2 d, c. P., Weigert's 

 fibrin stain m. B.) In this preparation examine the details already 

 mentioned and the elements of the stroma. 



Fallopian tubes. Cat. T.S. (p. 3,'inj., s. 22 & 24, c. P., m. B.) 

 (L) and (//) Externally a muscular coat (plain), to which 

 internally a folded mucosa, covered with ciliated epithelium, is 

 loosely attached. 



Uterus. Rabbit or Cat. T.S. (p. 3, inj., s. 22 & 24, c. P., m. B.) 

 (L) and (ff) The vascular mucous lining is closely packed with 

 long tubular glands (cubical and columnar spith) which have 

 duct-like openings upon the surface. Externally to this is the 

 circularly disposed plain muscle in many layers. 



Vagina. T.S. Cat. (p. 3, inj., c. P., m. B.) (L) and (//) 

 The surface epithelium is stratified squamous and rests upon 

 connective tissue, in which small papillary elevations are per- 

 ceptible. Mucous glands will be found in this layer, and 

 externally plain muscle mingled with connective tissue. 



29 Mammary gland. Human, non-lactating. (p. 11, s. 22 & 24, 



c. P., m. B.) (L) The glandular tissue is scanty and widely 

 separated by rather dense connective tissue. The ducts are 

 narrow. 



Mammary gland. Cat. Lactating. (p. 11, s. 13 & 17, c. P., m. B.) 

 The secreting structure occupies the whole gland, and the acini 

 are polygonal through distension and mutual compression. The 

 epithelium is closely packed along the walls, the ends of the cells 

 projecting irregularly into the lumen. Note the fat stained black 

 in the cells and in the contents of the lumen. Find the milk 

 ducts and their expansions in the nipple. The nipple is covered 



y epithelium, and on its sides small sebaceous
