wdth the anal fascia lining the undersurface of the levator ani muscle. At the sides it is firmly attached tothe bony rami. In front it is continuous with the dartos of the scrotumand the fascia of the penis. On account of its connections there is but one outlet for fluids, etc.,beneath it, and that is between the spines of the ))ubes on either side.The course of urine and other extravasations beneath it is therefore intothe scrotum and penis or on to the abdomen. THE MALE PERINEUM. 37 From this layer of fascia onward we have an aponeurotic layer alter-natino- with a layer of muscles etc., so that the latter are inclosed on twosides by fascia, the other two sides being formed by the rami of the pubicarch. From the superficial perineal fascia there is an incomplete medianseptum partly dividing the space into two lateral halves. In the exactmedian line of the perinseum there is therefore but little danger of hjemor-rhage, as even the bulb has a partial median septum, and apart from the

The bulb and corpus spongiosum are median in position. The bulbo-cavernosus or accelerator urin^e muscle surrounds the bulbat its posterior end. Farther forward it ))asses around the sides of thebulb to become attached to the triangular ligament; still farther forwardit passes around to meet in front of the corpus spongiosum; and the most 38 ANATOMY AXD PHYSIOLOGY OF THE
