The coccygeus muscle, which together with the levator ani makes up the pelvic diaphragm, lies on the internal surface of the sacrospinous ligament. Consequently, during the gluteal dissection, the sacrospinous ligament can be visualized from this perspective, but not the coccygeus as it lies deep to the ligament. An abdominal approach to the same region enables visualization of the coccygeus muscle overlying the sacrospinous ligament. Sites of attachment of the coccygeus muscle are the ischial spine laterally, and the coccyx posteromedially. The coccygeus muscle is innervated by sacral nerves 3 and 4.
