Pelvic diaphragm. The pelvic diaphragm is made up of (1) the coccygeus muscle and (2) the levator ani: the puborectalis pubococcygeus (or pubovisceral) and iliococcygeus muscles. Additional structures to note: arcus tendineus fascia pelvis, arcus tendineus levator ani, obturator internus muscle, piriformis muscle, ischial spine, obturator canal (Adapted from Figure 2.2 in Walters and Karram [8])
