Text Appearing Before Image:
l fascia (superficial perinaeal fascia) is thin,aponeurotic in structure, and of considerable strength, serving to bind down themuscles of the root of the penis. It is continuous, in front, with the dartos ofthe scrotum; on either side, it is firmly attached to the margins of the rami ofthe pubes and ischium, external to the crus penis, and as far back as the tuberosityof the ischium; posteriorly, it curves down behind the Transversus perinasi musclesto join the lower margin of the deep perinseal fascia. This fascia not only coversthe muscles in this region, but sends down a vertical septum from its under surface 746 SURGICAL ANATOMY OF THE PERINEUM. which separates the back part of the subjacent space into two, being incompletein front. In rupture of the anterior portion of the urethra, accompanied by extravasationof urine, the fluid makes its way forwards, beneath this fascia, into the areolar 390.—The Perinseum.

tissue of the scrotum, penis, and anterior and lateral portions of the abdomen; itrarely extends into the areolar tissue on the inner side of the thighs, or backwardsaround the anus. This limitation of the extravasated fluid to the parts above-named, is easy of explanation, when the attachments of the deep layer of thesuperficial fascia are considered. When this fascia is removed, the muscles con-nected with the penis and urethra will be exposed; these are, in the middle line,the Accelerator urinse; on each side, the Erector penis; and behind, the Trans-versus perineei. The Accelerator urince is placed in the middle line of the peringeum, immediatelyin front of the anus. It consists of two symmetrical halves, united along the medianline by a tendinous raphe. It arises from the central tendon of the peringeum,and from the median raphe in front. From this point, its fibres diverge like theplumes of a pen; the most posterior form a thin layer, which are lost on theanterior surface of the
