All the perineal muscles, through themedium of tendon and fascia, are directly or indirectly strongly con-nected with the pubic bones.

Through this diaphragm pass the lower portions of the rectum,anus, vagina, and urethra. FUNCTIONS OF THE PERINEUM AND PERINEAL REGION. It is clear from the foregoing paragraphs and illustrations that themuscles, fasciae, and ligaments of the perineal region constitute a mostessential supporting part of the pelvic floor. They surround, bindtogether, hold in position, support and maintain in their mechanicalrelations the terminal ends of the rectum, vagina, and urethra. Thereader is now prepared to take exception to the common notion thatthe pelvic organs derive their support from the small fleshy bodycalled the perineum. Another false idea is that the support is in thenature of that given by a keystone to an arch. The perineal regionand perineal body do not give support in the sense of being under thepelvic organs and holding them up as foundations. They are anessential an
