EXTERNAL ILIAC ARTERY, AND ITS BRANCHES. 235 



nal pudie has returned within the pelvis, and consists sometimes 

 in several branches. 



c. The Perineal Artery (Art. Perinea, Transversa Permit) 

 has its root near the origin of the transversus perinei muscle, 

 and advancing obliquely forwards is distributed in several ra- 

 mifications to the muscles and integuments of the perineum, 

 and to the posterior part of the scrotum. It is unavoidably cut 

 in the lateral operation for the stone. In the female it goes to 

 .the sphincter vaginae and to the labium externum. 



d. When the internal pudic has got beyond the transversus. 

 perinei muscle near the beginning of the crus penis, it detaches 

 to the bulb of the urethra, along the posterior margin of the tri- 

 angular ligament, a branch which penetrates to the corpus spon- 

 giosum, and is minutely distributed upon it, some of its ramifi- 

 cations reaching to the corpus cavernosum. This branch is 

 called by M. Chaussier, Urethro-bulbar, and instead of being 

 always distinct, it on some occasions comes from the Perineal. 



e. At the under part of the symphysis pubis, between it and . 

 the back of the penis, the internal pudic sends forwards, on the 

 dorsum of the penis, a superficial branch, (Ramus Superficialis 

 Dorsi Penis.) It advances to the end of the penis, under the 

 skin, being parallel with its fellow of the other side, and near to 

 it: sometimes the two unite after a short course. They are dis- 

 persed in branches to the integuments, and to the elastic liga- 

 ment of the penis. 



f. The Cavernous Artery of the Penis (Art. Cavernosa Pro- 

 funda Penis) may be considered as the terminating trunk of 

 the internal pudic. It penetrates the corpus cavernosum, be- 

 neath the symphysis of the pubes, and quickly divides into many 

 ramifications. The latter advance, and continue to subdivide 

 upon the cells of the corpus cavernosum, to which they are 

 principally distributed: some of them reach the corpus spongio- 

 sum urethra, and others anastomose with the corresponding ar- 

 teries of the other side.

 BRANCHES. 



The External Iliac Artery (Jlrteria lliaca Extern a) extends
