Dissection.—Slit up the internal spermatic (infundibuliform) fascia (Plate28), so as to expose the spermatic cord. Distinguish the elements of thespermatic cord, and trace the same beneath the peritoneum into the iliac fossa. 37. Elements of the Spermatic Cord.—These are : the vasdeferens, a hard, well-defined duct; the spermatic veins, arte-ries and nerves. The vas deferens winds abruptly, internally,behind the deep epigastric artery, to pass into the pelviccavity beneath the peritoneum ; the vessels and nerves con-tinue, superiorly, between the peritoneum and the iliac PLATE 22
