d) The uterine artery, Art. uterina, passes downwards to the 

 neck of the uterus, ascends in a tortuous course on the side of the 

 organ to its fundus, supplies branches to the vagina and Portio vaginalis 

 uteri and finally anastomoses with the ovarian (spermatic) artery. One 

 branch, which runs in the round ligament, reaches the inguinal canal 

 and communicates with the inferior epigastric artery. 



e) The internal or common pudic artery, Art. pudenda 

 communis, leaves the pelvis by the great sacro-sciatic foramen and reenters 

 it by the lesser sacro-sciatic foramen. It passes downwards on the 

 inner surface of the ischium, curves forwards and upwards towards the 

 pubic arch and divides here into the artery of the Corpus cavernosum 

 and the dorsal artery of the penis or clitoris. 



The branches of the internal pudic are: 



1. The middle h ae m o r r h o i d al, while still within the pelvis; 



2. The inferior h a e m o rr h o id al, two or three in number, pass 

 through the ischio-rectal space to the M. levator ani and the anus; 



3. The p e r i n e a 1 or superficial p e r i n e a 1, which passes for- 

 wards through the M. transversus perinei and gives off the posterior 

 s c r o t a 1 arteries in the male, the posterior labial in the female.
