three coats, an external or serous coat,a muscular, and a mucous coat. The serous coat is partial, andderived from the peritoneum, which invests the posterior surface andsides of the bladder, from about opposite the point of termination ofthe two ureters to its summit, whence it is guided to the anterior URINARY BLADDER. 605 wall of the abdomen by the hypogastric cords and oiachus. Themuscular coat consists of two layers, an external layer composed oflongitudinal fibres, the detrusor urinse; and an internal layer ofoblique and transverse fibres irregularly distributed. The anteriorlongitudinal fibres arise from the anterior ligaments of the bladder(tendons of the detrusor urinpe), the neck of that organ and the baseof the prostate gland, and spread out as they ascend to the fundus;they then converge upon the posterior surface of the organ and descendto its neck, where they are inserted into the isthmus of the prostategland, and into a ring of muscular tissue, which surrounds the com-

The divided surface of the os pubis. 2. The divided sui-face of the sacrum. 3. The body of the bladder. 4. Its fundus ; from the apex is seen passing upwards theurachus. 5. The base of the bladder. 6. The ureter. 7. The neck of the bladder. 8, 8. The pelvic fascia ; the fibres immediately above 7 are given otf from the pelvic fascia, and represent the anterior ligaments of the bladder. 9. The prostate gland. 10. The membranous portion of the urethra, between the two layers of the deep perineal fascia. 11 . The deep perineal fascia formed of two layers. 12. One of Cowper's glands between the two layers of deep perineal fascia, and beneath the membranous portion of the urethra. 13. The bulb of the corpus spongiosum. 14. The body of the corpus spongiosum. 15. The right crus penis. 16. The upper part ot the first portion of the rectum. 17. The recto-vesical fold of peritoneum. 18. The second portion of the rectum. 19. The right vesicula semmalis. 20. The vas deferens. 21. The rectum covered by the descending layer of the pelvic fascia, just as it is making its bend backwards to constitute the third portion. 22. A part of the levator ani muscle investing the lower part of the rectum. 23. The external sphincter ani. 24.
