FEMALE PERINEUM 181 



the prostate, and the method which should be adopted to 

 display the posterior surface of the gland will be described 

 when the investigation of the pelvic fascia is undertaken (see 

 p. 418). 



A pad of tow, soaked in preservative mixture, should 

 be placed in the perineum, and the flaps of skin carefully 

 stitched over it. On the fourth day after the body has been 

 brought into the dissecting-room, it is placed upon its back, 

 and the dissectors of the abdomen commence work upon 

 the abdominal wall, p. 197. 



FEMALE PERINEUM. 



The boundaries of the female perineum are identical with 

 those in the male (p. 147). The region is wider, however, 

 and of greater extent. For purposes of description it is sub- 

 divided, by an imaginary transverse line drawn in front of the 

 anus and the tuberosities of the ischia, into a posterior, anal 

 triangle, and an anterior, urogenital triangle. 



External Anatomy. The anal triangle presents the same 

 points for consideration as in the male. The external 

 anatomy of the urogenital triangle demands careful study, 

 because it includes the urethral opening and the external 

 organs of generation. The latter are 



1. The mons pubis. 



2. The labia majora. 



3. The labia minora. 



4. The clitoris. 



5. The urethral opening. 



6. The vaginal orifice. 



All the parts mentioned are included under the common 

 term of pudendum muliebre or Vulva. 



Mons Pubis (O.T. Mons Veneris). The mons pubis is a 

 marked cushion-like eminence situated in front of the pubes. 

 The projection is due to a collection of adipose tissue under 

 the integument. It is covered with hair. 



Labia Majora Pudendi. The labia majora correspond to 

 the two halves of the scrotum, separated from one another 

 by a median cleft. They are two rounded folds, which com- 

 mence anteriorly at the mons pubis, where they meet in the 

 anterior commissure. From the anterior commissure they 

 extend downwards and backwards towards the anus. As 

 they proceed backwards they diminish in thickness, and they 

 meet posteriorly in the posterior commissure. Laterally they
