the triangular ligament and within the substance of the 

 compressor urinae muscle to the anterior part of the space, 

 where it divides into the artery of the crus and the dorsal 

 artery of the penis. The latter continues the course of 

 the internal pudic forward and upward, perforating the 

 superficial layer of the triangular ligament close to the 

 opening for the dorsal vein of the penis, then passes between 

 the crura and symphysis pubis and through the suspensory 

 ligament of the penis to the dorsal surface of that organ, 

 where it lies external to the dorsal vein, which is centrally 

 placed. It continues along the dorsum of the penis to the 

 glans, where it ends by breaking up into a coronary anasto- 

 mosis. It also sends branches to the prepuce. The 

 dorsal artery is accompanied in its course by the nerve of 

 the same name which is placed outside of the artery. 

 Branches of the Internal Pudic. 



1 i ) The inferior hemorrhoidal branch (or branches, i 

 to 3) is given off as the pudic enters the rectovesical fossa. 

 It passes through the fat, filling the fossa, to the rectum 

 and anus. Above, it anastomoses with the middle hemor- 

 rhoidal of the anterior division of the internal iliac. (Con- 

 sult the intestinal anastomoses.) 



(2) The superficial perineal artery is given off at the 

 base of the triangular ligament, perforates the perineal 

 fascia, crosses over or behind the transverse perineal muscle, 

 extends forward between the erector and crus penis and the 

 accelerator urinae muscles, to the base of the scrotum, 

 where it ends in supplying the superficial parts of that 

 structure. It gives off the transverse perineal artery to the 

 muscle of that name, besides supplying the adjacent parts. 



(3) The artery to the bulb. This is a considerable 

 artery which arises from the internal pudic within the space 

 between the layers of the triangular ligament. Its course
