Pelvic floor components
The main structures forming the pelvic floor are the following:
Levator ani muslces - the most prominent component consisting of three muscles (puborectalis, pubococcygeus, iliococcygeus);
Coccygeus muscle - it is also called the ischiococcygeus muscle; posterior, smaller component;
Connective tissue structures, including fasciae that cover the pelvic floor muscles.
