Pubococcygeus Muscle, Superior View

Description

Viewed from above into the lesser pelvis of an adult male, the pubococcygeus forms the medial sheet of levator ani, arising from the posterior body of the pubis and adjacent tendinous arch of the obturator fascia, then sweeping posteriorly toward the anococcygeal raphe and coccyx. Flanking it laterally, the iliococcygeus spans from the tendinous arch toward the coccyx and lower sacrum, while puborectalis curves posteromedially to form a sling around the anorectal junction. Posteriorly, the sacrum and coccyx define the midline bony boundary, and the coccygeus (ischiococcygeus) lies posterolateral, running from the ischial spine to the sacrum and coccyx. A central pelvic hiatus interrupts the muscular diaphragm. A superior perspective is the clearest way to appreciate how the pubococcygeus and puborectalis narrow the urogenital hiatus and stabilize the anorectal angle. Small changes in tone here matter. Clinically, this anatomy frames the mechanism of male pelvic floor dysfunction, including post prostatectomy urinary incontinence and defecatory disorders when the levator plate weakens or the puborectalis sling fails to maintain the anorectal kink during increases in intra abdominal pressure. Use this artwork in pelvic anatomy and colorectal surgery teaching to orient learners to the levator ani subdivisions, the tendinous arch, and their relationship to the sacrum and coccyx, and in urology or physiotherapy materials discussing pelvic floor training and continence mechanisms in men. It also suits figures for manuscripts on levator avulsion, anorectal angle mechanics, and pelvic organ support. Anatomical accuracy verified by SciePro's Medical Advisory Board.
