The outlet of the pelvis is a lozenge-shaped space dividedby an imaginary line drawn in front of the anus, transverselybetween the anterior margin of the tuber ischii/into two parts,the ischiorectal region behind and the perineum in front. The ischiorectal region contains the external (m. sphincterani externus) and internal sphincters (m. sphincter ani inter* SURGICAL ANATOMY. 403 mis), the corrugator cutis ani and the ischiorectal fossa (fossaischwrectalis). The latter is a pyramidal cavity, its apexreaching to the junction of the obturator and anal fascia andits l>ase formed by the skin. It is bounded—. Behind, by the edge of the great sacrosciatic ligament andgluteus maximus muscle; internally, by the levator ani, coveredby the anal fascia, sphincter ani and coccygeus muscle; exter-nally, by the tuber ischii and obturator Artfrj of Cerpat Cavtnnmn0*r*at Artorg j/* Pent* Aritry f/ PaJie Arte C*rp*r* dam FIG. perineum, deep dissection.
