. Anatomy, descriptive and applied. Anatomy. 442 THE MUSCLES AND FASCIA down the muscle of the root of the penis. It is continuous with the dartos of the scrotum, with the fascia of the penis, and with Scarpa's fascia on the anterior surface of the abdomen; on either side it is firmly attached to the outer lip of the ischiopubic ramus. Posteriorly (dorsally) the deep layer curves around the superficial transverse perineal muscle to blend with the base of the triangular ligament. The deep (cephalic) surface of this fascia covers the superficial mus- cles and the superficial bloodvessels and nerves of the perineum (Fig. 333). From its deep surface a septum which is incomplete in front is given off and divides the adjacent space in two. The Central Tendinous Point of the Perineum.—This is a fibrous point in the middle line of the pelvic outlet, between the urethra and the rectum, and about half an inch in front of the anus. At this point four muscles converge and are attached—viz., the External sphincter ani, the Accelerator urinae, and the two Superficial transverse perineal; so that by the contraction of these muscles, which extend in opposite directions, it serves as a fixed point of support (Fig. 333)..

Compressor urethrae. The Superficial transverse perineal muscle (to. transversus perinei superficialis) is a narrow muscular slip, which passes more or less transversely across the pelvic outlet. It arises by a small tendon from the inner and fore part of the tuberosity of the ischium, and, passing inward, is inserted into the central tendinous point of the perineum, joining in this situation with the musc
