224 THE POCKET ANATOMY 



near the base, in either a blind extremity or by anastomotic 

 loops, becoming straighter near the apex ; as they enter the 

 mediastinum, they coalesce together to form twenty or thirty 

 tubuli recti. 



The tubuli recti or vasa recta pierce the mediastinum, inter- 

 lace, and form the vete testis. 



Above twelve to twenty tubules pass from the upper part of 

 the rete as the vasa efferentia. 



The vasa efferentia perforate tunica albuginea, being at first 

 straight, then convoluted, and as the coni vasculosi form the 

 globus major. 



The coni open into the excretory duct at intervals (when 

 unravelled) of about 3 inches. 



The vas deferens commences at the lower part of the globus 

 minor, and ascends along the inner side of the posterior part 

 of the epididymis ; thence it follows the spermatic cord through 

 the inguinal canal and internal abdominal ring. Here it lies 

 under the peritoneum and passes inwards, crossing to the 

 inner side of the external iliac artery, and, entering the pelvis, 

 arches over the superior surface of the bladder, crossing the 

 obliterated hypogastric artery and ureter. At the base of the 

 bladder it runs along the inner side of the vesiculas seminales 

 and loses its peritoneal covering, being separated from the 

 rectum by the recto-vesical fascia, here becoming sacculated ; 

 narrowing again at the base of the prostate, it unites with 

 the duct of the vesicula seminalis of the same side, and forms 

 the common ejaculatoiy duct, which passes forwards through 

 the prostate and opens on the lateral margin of the sinus 

 pocularis into the prostatic urethra. 



THE VESICULA SEMINALES. 



The vesiculse seminales are two sacculated pouches, placed 

 between the base of the bladder in front and the rectum 

 behind. They are pyramidal in shape, the posterior part 

 being the wider ; anteriorly they converge to enter the 

 prostate near the middle line. The corresponding vas deierens 

 lies on the inner side. 



THE FEMALE ORGANS OF GENERATION. 



The external organs of generation in the female are : the 

 mons veneris, the labia majora, the labia minora, the clitoris, 

 the meatus urinarius, and the orifice of the vagina. The term 

 vulva includes the whole of these.
