(The rectum has been drawn somewhat to the left, the peritonaeum has been removed.) 



^- 2. A. deferentialis (0. T. artery of the vas deferens) (present only in the male), fre- 

 quently arising from the preceding arteiy or from the following, passes forward and downward 

 to the ductus deferens, there divides, one part going downward as far as the vesicula seminalis, 

 'the other upward to the inguinal canal and thence to the epididymis; it anastomoses there 

 with the a. testicularis. 



^^ 3. A. vesicalis inferior (see also Figs. 471 and 472) goes downward to the fundus vesicae: 

 it goes also in the male to the vesicula seminalis and the prostate, in the female to the vagina. 

 ^^ 4. A. baemorrhoidalis media (middle haemorrhoidal artery) (see also Fig. 467) comes 

 ftequently from the a. pudenda mterna and runs over the m. coccygeus and m. levator ani, 

 downward and medianward to the rectum and to the surrounding muscles ; it gives off branches 

 to the vesiculae seminales and to the prostate in the male, to the vagina in the female.
