Pelvic floor
Anatomical structure / From Wikipedia, the free encyclopedia
The pelvic floor or pelvic diaphragm is an anatomical location in the human body,[1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs.[2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.[3] and separates between the pelvic cavity from above, and the perineum from below.[citation needed] It is formed by the levator ani muscle and coccygeus muscle, and associated connective tissue.[4]

The pelvic floor has two hiatuses (gaps): (anteriorly) the urogenital hiatus through which urethra and vagina pass, and (posteriorly) the rectal hiatus through which the anal canal passes.[5]
