THE TESTICLES AND THEIR COVERINGS J 377 The cremasteric artery (a. spermatica externa) is a branch of the deep epigastric artery. It accorapjinics the s;)erniiitic cord and supplies the Cremaster muscle and other coverings of the cord, aiiMstoiiinsiiii; with the spermatic and deferential arteries. The spermatic veins (Figs. 523 and 1146) emerge from the back of the testis and receive tributaries from the epididymis; they unite and form a convoluted plexus, the pampiniform plexus (plexus pampiniformis), which forms the chief mass of the cord; the ves.sels composing this plexus are very numerous, and ascend along the cord in front of the vas deferens; below the external or superficial abdominal ring they unite to form three or four veins, which pass along the inguinal canal, and, entering the abdomen through the internal or deep abdominal ring, coalesce to form two veins. These again unite to form a single vein, which opens on the right side into the inferior vciki cava at an acute angle, and on the left side into the left renal vein at a right angle. The lymphatic vessels of the scrotum terminate in the superficial inguinal nodes. The lym- phatics of the testicle join the lymphatics of the epididymis and of the visceral layer of the vaginal tunic of the testicle, and ascend in the spermatic cord. They reach the lumbar region along the spermatic bloodvessels and terminate in the lateral aortic nodes, and sometimes in the nodes in front of the aorta. The lymphatics of the seminal duct pass to the external iliac nodes. The nerves are the spermatic plexus from the sympathetic, joined by filaments from the pelvic plexus which accompany the artery of the vas deferens.

Fig. 114G.—Spermatic veins. (Testut.) The testes (Figs. 1141 and 1146) are suspended in the scrotum by the spermatic cords, the left testis hanging somewhat lower than its fellow. The average dimen- sions of this gland are from one and a half to two inches (4 cm.) in length, one inch (2.5 cm.) in breadth, and an inch and a quarter (3 cm.) in the antero-posterior diameter, and the weight varies from six to eight drams (25 to 30 grams). It is of a grayish-white color, and of resilient consistency. Each gland is of an oval 87
