VISCERA IN THE FEMALE. 500 



the urethra is conducted. Besides the attachment of the corpora cavernosa 

 to the bone, the body of the penis is connected with the front of the 

 symphysis pubis by the suspensory ligament. 



The corpus spongiosum urethra incloses the urethral canal in front of 

 the triangular ligament, and forms the head of the penis. It is a vascular 

 and erectile texture, like the corpora cavernosa, but is much less strong. 

 Commencing posteriorly by a dilated part the bulb, it extends forwards 

 around the urethra to the extremity of the penis, where it swells into the 

 conical glans penis. 



The bulb (fig. 174, d) is directed backwards, slightly, below the mem- 

 branous part of the urethra, and is fixed by fibrous tissue to the front of 

 the triangular ligament. The ejaculator urinae muscles cover it. This 

 enlargement presents usually a central depression, with a bulging on each 

 side, and is subdivided into two lobes. 



The glans penis (fig. 181, /) is somewhat conical in form, and covers 

 the truncated end of the corpora cavernosa. Its base is directed back- 

 wards, and is marked by a slightly prominent border the corona glandis; 

 it is sloped obliquely along the under aspect, from the apex to the base. 

 In the apex is a vertical slit, in which the urethral canal terminates ; and 

 below that aperture is an excavation, which contains the piece of the 

 teguments named frcenum preputii. 



SECTION III. 



CONNECTIONS OF THE VISCERA IN THE FEMALE. 



IN the pelvis of the female are contained the lower end of the intestinal 

 tube, and the bladder and urethra, as in the male ; but there are in 

 addition the uterus with its accessories, and the vagina. 



Position. The rectum is posterior to the rest as in the male pelvis, and 

 forms a like curve. In the concavity of the bent intestine lie the uterus 

 with its appendages, and the tube of the vagina. And in front of all are 

 the bladder and the urethral canal. Thus there are three tubes connected 

 with the viscera in this sex, viz., the urethra, the vagina, and the rectum ; 

 and all are directed forwards, one above another, to the surface. 



Directions. The description in Section I. (p. 499) must be used for 

 instructions respecting the removal of the innominate bone, and the dis- 

 tension of the viscera; also for the muscles of the pelvic outlet and the 

 anatomy of the fasciae. After the student has learnt the muscles and the 

 fascia, p. 499, which are nearly alike in both se^es, he may make the 

 following special dissection of the viscera of the female pelvis. 



Dissection. On taking away the recto-vesical fascia and much fat, the 

 viscera will come into view. To maintain the position of the uterus, raise 

 it up with a piece of string passed through the upper part. The reflec- 

 tions of the peritoneum on the viscera are to be preserved ; and a piece of 

 cotton wool is to be placed between the rectum and the uterus. 



The obliterated cord of the internal iliac artery is to be followed on the 

 bladder; and the ureter is to be traced forwards by the side of the uterus 

 to the bladder. Afterwards the urethra, the vagina, and the rectum are
