Under this head are included—1, the testes with their ducts andcoverings ; and, 2, the urethra, with certain accessory parts, such as theprostate and Cowpers glands. The urethra in the male is at once theoutlet for the urine from the bladder and the products of secretion fromthe sexual glands. Extending from the neck of the bladder to theextremity of the penis, it is surrounded in its first part by the prostategland, and there receives the excretory ducts of the testes and vesicuteseminalcs ; its second part passes through the triangular ligament of theperineum ; and its third and longest part passes along the perineum andpenis, surrounded by the corpus spongiosum. THE PEOSTATE GLAND. 669 THE PROSTATE T^he prostate gland is a firm, glandular, and muscular body, somewhatresembling a chestnut in shape and size, which adjoins the neck of thebladder, and encloses the first part of the urethra : it is placed in thepelvic cavity, on the upper aspect of the subpubic fascia, and restsposteriorly against the rectum. Its posterior or rectal surface is largerthan its flattened anterior or pubic surface. It usually measures aboutan inch and a half across at its widest part, an inch and a quarter fromits base to its apex, and nearly an inch in thickness. Its ordinaryweight is about six drachms. The pubic surface of the prostate is flattened and marked with aslight longitudinal fiirrow ; it is about half an inch or rather more fromthe pubic symphysis, and there, as well as at the sides, the gland is con-Fig. 582.—Tkansverse section of the pros-tate GLAND THROUGH THE MIDDLE.
