erted into the central tendinous point of the perinaeum, joining inthis situation with the muscle of the opposite side, the External sphincter anibehind, and the Accelerator urinte in front. Nerve-supply.—The perineal branch of the internal pudic. Actions.—By their contraction they serve to j&x the central tendinous pointof the perinseum. The Accelerator urinse (Ejaculator seminis, or Bidbo-cavernosus) is placed inthe middle line of the perinseum, immediately in front of the anus. In consistsof two symmetrical halves, united along the median line by a tendinous raphe.It arises from the central tendon of the perinaeum, and from the median raphein front. From this point its fibres diverge like the plumes of a pen ; the mostposterior form a thin layer, which are lost on the anterior surface of the triangularligament; the middle fibres encircle the bulb and adjacent parts of the corpus Fig. 336.—The superficial muscles and vessels of the perinseum.

The latter fibres are best seen by dividing themuscle longitudinally, and dissecting it outwards from the surface of the urethra.Action.—This muscle serves to empty the canal of the urethra, after thebladder has expelled its contents ; during the greater part of the act of micturitionits fibres are relaxed, and it only comes into action at the end of the process.The middle fibres are supposed, by Krause, to assist in the erection of the corpusspongiosum, by c
