Surgical anatomy : a treatise on human anatomy in its application to the practice of medicine and surgery . ormed by the acceleratoresurinffi ; the base of each triangle, by the transverse perineal; and the hjpothenuse,by the erector penis. The Accelerator Urinas Muscle (ejaculator seminis, or bulbo-cavernosus) lies onthe bulb of the corpus spongiosum and the portion of the corpus spongiosum justanterior to the bulb. It is a double muscle, the two halves being united inthe middle line on the superficial surface of the bulb by a median tendon orraphe. It consists of three sets of fibers—posterior, middle, and anterior. Theposterior fibers are inserted into the anterior layer of the triangular ligament oneach side of the bulb, and some of the most posterior fibers are inserted beneaththe crus penis into the middle of the ischio-pubic ramus; the middle fibers sur-round the bulb and the adjacent part of the corpus spongiosum, and join the fibers PLATE CGCL Corpus spongiosuDorsal penisArteries of corpus cavernosu Dorsal penisCrus penis Erector penis m.

Action.—The action of the accelerator urinse muscle as a whole is to compressthe bulb and to expel the last drop of urine in tliis part of the urethra, after thebladder has been emptied. It also assists in expelling the semen. The middlefibers, according to Krause, assist in the erection of the corpus spo
