Quick Summary

The urogenital diaphragm is a muscular partition that separates the pelvic cavity from the perineum. In males, the urethra passes through this diaphragm, carrying both urine and semen. The female urethra, which is shorter, also passes through the urogenital diaphragm and carries only urine. This diaphragm plays a role in the urinary system by surrounding the urethra with the sphincter urethrae muscle, which helps control the flow of urine. The urinary bladder, a muscular organ that stores urine, rests on the pelvic floor, supported by muscles like the levator ani.12
