The inguinal or spermatic canal (canalis inguinalis) (Figs. 332 and 1127) 

 contains the spermatic cord in the male and the round ligament in^ the female. 

 It is an oblique canal, about

 mences above at the internal 

 or deep abdominal ring, which 

 is the point where the cord 

 enters the inguinal canal, and 

 terminates below at the ex- 

 ternal or superficial ring. It 

 is bounded, in front, by the 

 integument and superficial 

 fascia, by the aponeurosis of 

 the External oblique through- 

 out its whole length, and by 

 the Internal oblique for its 

 outer third; behind, by the 

 triangular fascia, the conjoined 

 tendon of the Internal oblique 

 and Transversalis, transver- 

 salis fascia, and the subperi- 

 toneal fat and peritoneum; 

 above, by the arched fibres of the Internal oblique and Transversalis; below, 

 by the union of the transversalis fascia with Poupart's ligament.
