The dissector having examined the formation of the exter-nal rino-, may now endeavour to trace the fibres of the cremas-ter muscle, which pass out through it, being sent from theunder edcre of the internal oblique. These fibres generallypass down in a semicircular form, having one portion occa-sionally attached to the pubis. He may now make an inci-sion in the course of Pouparts ligament, commencing abovethe external ring, almost in a semicircular manner; this will18* 210 THE DISSECTORS GUIDE. enable him to examine the internal ring and inguinal canal,which the following diagram proposes to elucidate. d. a. The spermatic cord* passing through the external abdominal ring,wilh fibres of the cremaster muscle seen upon it. b. The external abdominal ring. f. The tendon of the external oblique, reflected by an incision made inthe course of Pouparts ligament, carried above the ring toward the lineaalba, for the purpose of showing the inguinal canal and internal ring. d. The inguinal canal, situated between the two rings. The bounda-ries of this canal consist of the tendon of the external oblique on theanterior part or towards the skin, the internal oblique at the upper part,Pouparts ligament at the lower pait, and the transversalis muscle andfascia at the posterior part, or towards the abdomen. e. The internal rinjr, formed by the fascia transversalis, and the epi-gastric artery, seen passing round the inner part of the internal
