This fascia and the dartos aided by the Bulbo cavernosi and the [schio-cavernosi muscles compress the veins of the penis in the action of erec- tion. Blood Supply.—The arteries to the penis are branches of the internal pudic. (a) The artery of the bulb, which goes to the bulb of the corpus spon- giosum, (hi the arteries of the corpora cavernosa, (c) the dorsal artery of the penis. The envelops of the penis are supplied by the external pudic, the superficial perineal, and the dorsal artery. The veins of the penis are in two sets, (a) superficial veins, which pass between the dartos and fascial sheath end in the long saphenous and femoral veins, (b) the deep veins, which drain the corpora cavernosa, corpus spongiosum, end in the deep dorsal vein and in the internal pudic vein. Lymphatics of the penis are divided into two sets, (a) superficial ones which pass to the inguinal nodes, and (b) deep ones which empty into the pelvic and Lumbar nodes as well as in the inguinal nodes. Nerve Supply.—The genital branch of the genito-crural and the super- ficial perineal branches of the pudic supply the covering of the penis, while the dorsal nerve of the penis, and superficial perineal, and hypogastric plexus sup- ply the erectile bodies. PLATE SEMICIRCULAR CANAL 5CALA TYMPANI INFERIOR Interior of Bony Labyrinth. The spermatic cord is about four inches long and extends from the internal abdominal ring to the globus minor of the epididymis. It passes through the inguinal canal. It is composed of the following structures held together by areolar tissue and invested by layers broughl down by the descent of the testicle. 1. The vas deferens, which is the excretory duct of the testicle passing from the testis to the ejaculatory dud. It is recognizable by its cord-like resistance t
