SPERMATIC CORD. Each spermatic cord consists of an artery and vein, and nerves, together with the duct, vas deferens. These constituents are united by cellular tissue, which may be the remains of that canal of peri- toneum peculiar to foetal life. It is covered by the fascia transversalis prolonged from the abdo- men, and also the cremaster muscle, which has been previously de- scribed. The spermatic artery comes from the aorta, and sometimes from the renal. It is tortuous, and after passing through the rings divides into two or three branches ; the termination of the artery is larger than its origin. The spermatic veins are very tortuous and numerous, and on account of their vine-like appearance are termed vasa pam^pini- formia. The seat of circocele. The external spermatic nerves^ and also branches of the abdomino- crural, supply the muscular structure; filaments of the sympathetic run also to the testicle. The vas deferens is a continuation of the epididymis. Passing through the cord and rings, it descends behind the bladder and joins the duct of the vesiculse seminales. It is very hard, and readily recognised by touch ; its walls are extremely thick, and its bore almost capillary. It is nearly white, and thicker than a knitting needle. THE PERINEUM. The perineum is that space included between the anus, arch of the pubis, and the tu- Fig. 104. berosities of the ischia, and a correct know- ledge of it is of great importance to a sur- geon. In a proper dissec- tion the removal of the skin reveals the super- ficial fascia^ which is continuous with the superficial fascia of other parts of the body. When this is removed, the perineal fascia is exhibited, which is a dense, thin, and tough fascia,*^ adhering to the rami of the pubes and ischium on each side; in front it is co
