. Cunningham's Text-book of anatomy. Anatomy. ax. Abdominal cavity. Processus vaginalis. t. Testis. s. Scrotum. Tunica vaginalis. x. Kudimentum pro- cessus vaginalis. External spermatic fascia I Tnfundibuliform fascia I Testicular artery Pampinilon / ,.v plexus Funiculus Spermaticus (Spermatic Cord). The testis in its course downwards through the abdominal wall into the scrotum takes with it its duct—the ductus deferens—blood and lymph vessels, and nerves of supply. All these lie together in the inguinal canal as they traverse the abdominal wall, and when they leave the canal by the subcutaneous inguinal ring they extend downwards to the posterior border of the testis. The ductus deferens, the spermatic vessels, and the nerves and lymph vessels of the testis, loosely con- nected together, form the funiculus sper- maticus, or spermatic cord. At the ab- dominal inguinal ring its constituent parts separate from one another, and the funi- culus may therefore be considered to extend from the abdominal inguinal ring to the posterior border of the testis. The struc- tures which form the funiculus spermaticus are enclosed within a number of coverings derived from the layers of the anterior abdominal wall, and these, when the con- stituents of the funiculus reach the posterior border of the testis, surround the tunica vaginalis, and so form a part of the wall of the scrotum. The sheaths or coverings of the cord derived from the abdominal wall are three in number, and are named intercolumnar fascia, fascia cremasterica, and infundibuliform fascia. The intercolumnar fascia is the most superficial of the three sheaths, and is derived from the aponeurosis of the external oblique muscle,.
