UROGENITAL SYSTEM. 



The skin covering them resembles that on the inner surface 

 of the labia majora. [1195] 



The vestibule is the cleft between the labia mihora and behind 

 the glans clitoridis; on its floor are the openings of the ure- 

 thra, vagina, and ducts of Bartholin's glands; its posterior 

 part, between the fourchette and vaginal orifice, is the fossa 

 navicularis. The external urethral orifice lies just in front of 

 the vaginal orifice. [1196] 



Clitoris. This represents the penis and has a body, two 

 crura, and a glans, but is not traversed by the urethra. The 

 body consists chiefly of erectile tissue, is an inch to an inch and 

 a half long, bent with the convexity upward, and tapers dis- 

 tally. It is enclosed in a fibrous coat and divided by an incom- 

 plete septum into two symmetrical and cylindrical corpora 

 cavernosa; a suspensory ligament runs from the fibrous coat 

 to the symphysis. The glans is a small mass of erectile tissue 

 on the pointed end of the body ; a fold (prepuce) covers it and 

 another (frenulum) is attached inferiorly, both being contin- 

 uous with the labia minora. The crura are the corpora cav- 

 ernosa, which diverge posteriorly to be attached to the sides of 

 the pubic arch ; each is covered by the Erector clitoridis and 

 has a fibrous sheath. [1197] 



Bulbus Vestibuli. This is a mass of erectile tissue which 

 corresponds to the corpus spongiosum. It consists of two lat- 

 eral halves which lie on either side of the vaginal wall, upon 

 the triangular ligament; these taper in front where they are 

 joined, above the urethra, by a narrow median part (pars in- 

 termedia) continuous with the glans. The Bulbo-cavernosus 

 covers each lateral part. [1198] 



Glands of Bartholin. These are the size and shape of a 

 small bean and represent Cowper's glands. One lies on each 

 side of the lower part of the vagina, covered by the Bulbo- 

 cavernosus and often overlapped by the bulb: a long duct 

 opens on the vestibule between the vaginal orifice and the 

 labium minus. [1198]
