VESICAL ARTERIES.

of deficient pudic arteries replace one or more of tlieii- branches, as will be more 

 fully noticed tinder those arteries. 



Besides the superior and inferior vesical arteries, other smaller branches will 

 be found to reach the bladder, and usually one slender vessel which is distiibuted 

 particularly to the under surface of the vesiculK seminales.

 THE Visceral and Pudio Arteries (from 11. Quain). ^ 



a, the OS pubis divided a little to the left of the symphysis ; i, placed close to the 

 upper pait of the urinary bladder, upon which lies the vas deferens ; c, placed on the 

 ujiper part of the rectum, near the left ureter ; c', at the junction of the middle and lower 

 parts of the rectum jjoints to the vesicula seminalis ; c", the anus ; d, the urethral bulb ; 

 <■, the eras penis divided ; /, the short sacro-sciatic ligament attached to the spine of the 

 ischium; 1, common iliac artery ; '2, internal iliac artery ; 3, gluteal artery cut short : 

 4, common trunk of the sciatic and pudic arteries ; 4', sciatic artei'y cut as it is passing 

 out of the great sacro-sciatic foramen ; 5, placed on the divided surface of the ischium 

 near the spine, points to the pudic artery as it is about to re-enter the pelvis by the 

 lesser sacro-sciatic foramen ; 5', the superficial perineal branches of the pudic ; 5", the 

 pudic artery, proceeding to give the artery of the bulb, and passing on to give 6, the 

 artery of the crus penis and the dorsal artery of the penis ; 7, placed on the middle part 

 of the rectum, points to the descending branches of the superior hiemorrhoidal artery ; 8, 

 the superior and middle vesical arteries ; 9, the inferior vesical artery, of considerable 

 size in this instance, giving branches to the bladder, the vesicula seminalis, the rectum 

 (middle hsemorrhoidal), and 9', to the prostate gland. 



Middle hssmorrhoidal artery. — This branch is usually supplied to 

 the rectum by the interior vesical artery, but sometimes proceeds from 

 other sources. It anastomoses with the branches of the other ha3mor- 

 rhoidal arteries. 



The uterine artery is directed downwards from the anterior divi- 

 sion of the internal iliac artery towards the neck of the uterus. 

 Insinuating itself between the layers of the broad ligament, it passes 

 upwards on the side of the uterus, pm'suing an exceedingly tortuous 

 course, and sends off numerous branches, which enter the substance of 

 that organ.
