Dissection of male inguinal region and spermatic cord
Internal aspect of deep inguinal ring and related structures of right side
The specimen is viewed from above and from the left with the anterior abdominal wall pulled forward (toward the top of the photograph). Peritoneum has been preserved in a small area immediately lateral to the deep inguinal ring and, above this, on the interior of the abdominal wall. A small, persistent processus vaginalis (15) is present. It extends as a narrow tube through the deep ingnuinal ring into the upper end of the inguinal canal.

2 . Upper pointer: Femoral ring Lower pointer: Lacunar ligament
3 . Pubic symphysis
4 . Pectineal ligament (Cooper's ligament)
5 . Upper pointer: Ductus deferens (accompanied by artery of ductus deferens and filaments from pelvic plexus of nerves) Lower pointer: Lateral umbilical ligament
6 . Obturator artery (entering obturator canal)
7 . Fascia covering obturator internus muscles
