ANATOMY IN A NUTSHELL. 



1. The isthmus is the inner constricted third of the tube which is hard, 

 cylindrical, and nearly horizontal. It is about an inch and a half long and 

 one-eighth of an inch in diameter. 



2. The ampulla (receptaculum seminis) is the outer dilated portion curving 

 over the ovary and extends from the isthmus to the fimbriated extremity. Its 

 diameter is about twice that of the isthmus and its walls are thinner and softer. 

 The isthmus and the ampulla make the body of the tube. 



3. The Iniundibulum is the expanded outer end. the opening of which is 

 the ostium abdominale. 



4. The fimbriae are fringe-like processes which are arranged in two or three 

 concentric circles. The frimbria ovarica is larger than its fellows and is at- 

 tached to the superior extremity of the ovary. 



5. The hydatid of Morgagni is the cyst like remnant of the Mullerian duct 

 attached to the oviduct by a long stalk of peritoneum.

The ovaries, which are the essential female organs of generation, are two 



grayish pink bodies situated in the broad ligament behind ami below the Fallo- 

 pian tube. The position of the ovary is indicated on the body by the mid- 

 point of a line drawn from the anterior superior spinous process of the ilium to 

 symphysis pubis. 



The dimensions of the ovary arc one and a half, by three-fourths, by one- 

 third of an inch. They are not so dense as the ^esticle and in old age atrophiy.
