FEMORAL ARTERY. 



413 



internal abdominal ring, thus crossing the spermatic cord on the 

 inside. It supplies the rectus muscle and other portions of the 

 abdominal parietes, anastomosing with the circumflex ilii and 

 anterior abdominal arteries. The external jnidic artery descends 

 to tlie dorsum penis, 

 through the inguinal 

 canal, where itbecomes 

 the dorsal artery of 

 the jDenis, and divides 

 into anterior and pos- 

 terior. The anterior 

 is long and flexuous, 

 so as to allow protru- 

 sion of the penis ; it 

 runs along to the an- 

 terior extremity, sup- 

 plying the erectile 

 tissue. The posterior 

 also passes to the 

 dorsum, and anasto- 

 moses with the inter- 

 nal pudic and obtura- 

 tor, supplying the 

 scrotum. 



The external pudic 

 gives off the subcu- 

 taneous abdominal 

 artery which passes 

 forwards through the 

 inguinal canal, and 

 over the abdominal 

 fascia, reaching the 

 anterior extremity of 

 the suspensory liga- 

 ment of the sheath, 

 where it terminates 

 by numerous subcu- 

 taneous twigs supplying the skin, sheath, and superficial inguinal 

 glands, one twig circling round the umbilicus to inosculate with 

 its fellow from the opposite side. In the female, the mammary 

 replaces the dorsal artery of the penis ; it is much larger
