250 Hypogaftric Artery y &V. [Book IX. 



corpora cavernofa take their origin ; at this place it is 

 divided into feveral fmaller branches, which are diftri- 

 buted on the corpora cavernofa, the bulb of the ure- 

 thra, and the anus. The fecond principal branch, 

 fometimes called the pudica externa, runs between the 

 bladder and rectum. 



The hxmorrhoidalis media proceeds from thepudica 

 interna, or Ibme of the other large branches ; it goes 

 to the lower part of the rectum, and fends twigs to the 

 bladder, veficulas feminales, and prottate gland. The 

 arteria obruratrix perforates the obturator mufcles, and 

 is distributed to the neighbouring mufcles. 



The hypogaftric, or internal iliac artery, having fent 

 off all thefe branches to the parts about the pelvis, af- 

 cends on the fide of the bladder towards the navel, 

 where it meets its fellow of the oppofite fide. Thefe 

 arteries, near the navel, are in the adult contracted into 

 the appearance of a ligament, and are quite clofed j in 

 the foetus, however, they are a continuation of the 

 trunk of the hypogaftric arteries by which the circula- 

 tion is carried on between it and the placenta. 



It has been already mentioned, that the external iliac 

 artery pafTcs out of the abdomen under Fallopius's li- 

 gament ; it here gives off two considerable branches ; . 

 one of thefe, the arteria epigaftrica, runs upwards on the 

 mufcles at the anterior part of the abdomen, and com- 

 municates freely with the mammaria interna; the other 

 branch, fent off from the external iliac at this place, 

 runs to the internal edge of the os ileum, and is ramified 

 on the oblique and tranfverfe mufcles of the abdomen, 

 communicating with the lumbar arteries. 



After it has pa(Ted under the ligament of Fallopius, 

 the external iliac changes its name to that of the crural 

 or femoral artery. It fends off, firft, three fmall 

 branches ; one, the pudica externa, goes to the inguinal 



^ glands,
