THE PERINEAL BODY. 231 The erectores clitoridis are not properly included in this dissection,and are described with the clitoris. Removing the bulbo-cavernosi and the vaginal bulbs, which restupon the anterior layer of the triangular ligament, the latter is seento he perforated by branches of the pudic arteries and nerves and by Fig. Perineal Septum, posterior view (Savage); S, posterior surface of symphysis; U, urethra; Vtvagina; l. pubic attachment of bladder; 2, pubic attachment of levatorani (pubo-coccyg-eus); ??.lino of attachment of obturato-coccygeus; 1, pudic vein; 5, urethro-pubic plexusof veins; 6, posterior surface of septum; 7, median portion of pubo-coccygeus, enteringperinea] body at lower edge of septum. the communicating veins which extend from the bulbs and clitoristo the vesical plexuses. When the layer itself is detached, the follow-in- structures are exposed : The urethra, surrounded by the compressorurethra1 of Guthrie, the constrictor vaginae of some authors;2 the deeptransversus perinei, the vulvo-vaginal glands, internal pudic vesselsand nerves, dorsal vein and nerve of the clitoris, and artery of thebulb. The two former muscles are described by Heath as forming afigure-of-8 around the urethra and vagina, being attached anteriorly tothe posterior aspect of the pubic
