also generally gives off the (b) middle vesical to the 

 base of the bladder. 



(c) The inferior vesical vaginal in the female 

 joins its fellow. It supplies the bladder, prostate 

 gland, and seminal vesicles; in the female, vagina, and 

 rectum. 



(d) The middle hemorrhoidal arises with the pre- 

 ceding, and runs to the rectum to join other hemor- 

 rhoidal arteries. 



(e) The uterine in the female ascends in the broad 

 ligament from the cervix along the side of the uterus, 

 and joins the ovarian artery. 



(/) The obturator runs forward below the pelvic 

 brim, between the peritoneum and pelvic fascia below 

 the nerve, then through the upper part of the obtura- 

 tor foramen, dividing beneath the obturator externus 

 into an external and an internal branch. 



The termination of the anterior trunk of the internal 

 iliac then divides into two branches, the sciatic and 

 the internal pudic arteries. 



The external iliac artery extends from the division 

 of the common iliac to the midpoint between the 

 symphysis of the pubis and the anterior superior 

 spine of the ilium, behind Poupart's ligament. 



The Arteries of the Lower Extremity. THE FEMORAL 

 ARTERY. The femoral artery continues the external 

 iliac artery down into the thigh to end at the opening 

 in the adductor magnus at the junction of the upper 

 three-fourths and lower one-fourth of the femur. 

 From its beginning to the point where the profunda 

 femoris is given off, it is called the common femoral, 

 below this the superficial femoral. Its upper part 

 lies in Scarpa's triangle, bounded above by Poupart's 

 ligament, the inner side formed by the inner margin 

 of the adductor longus, the outer by the sartorius. 

 Its floor, from without inward, is made up of the 

 iliacus, psoas, pectineus, and adductor brevis. The 

 lower part runs in Hunter's canal, a depression between
