Rete testis. a long course, reaches the posterior border of the testis, where it breaks up into branches which enter the mediastinum testis, and are distributed along the septa and on the deep surface of the tunica albuginea. The veins issuing from the posterior border of the testis form a dense plexus, called the plexus pampiniformis, which finally pours its blood through the spermatic vein, on the right side, into the inferior vena cava; on the left side the spermatic vein joins the left renal vein. The nerves for the testis accompany the internal spermatic artery, and are derived through the aortic and renal plexuses from the tenth thoracic segment of the spinal medulla. The afferent fibres from the epididymis appear to reach the spinal medulla through the posterior roots of the eleventh and twelfth thoracic and first lumbar nerves. The arteries and nerves of the testis communicate with those on the lower part of the ductus deferens, namely, with the artery of the ductus deferens and with twigs from the hypogastric plexus. The lymph-vessels of the testis pass upwards in the spermatic cord, and end in the lumbar lymph-glands. DUCTUS DEFERENS. The ductus deferens ( vas deferens) is the direct continuation of the duct of the epididymis. Beginning at the inferior extremity of the epididymis, it ends, after a course of nearly 18 inches, by opening as the ejaculatory duct into the prostatic or first part of the urethra. The duct in parts of its course is somewhat convoluted, and the actual distance t
