The English name of the levator ani is the muscle that lifts the ring. This muscle has two parts. The English equivalent of the pubococcygeus part of the muscle is the part between the adulthood bone and the cuckoo bone.Levator comes from the Latin verb levare meaning “to lift.”The word ani is the genitive form of anus, which comes from the Latin for “ring.” This describes the ring-like structure of the anus.Pubococcygeus comes from the Latin puber, which denoted “an adult of marriageable age.” The noun form of this word literally meant “the time of coming of hairs,” in reference to the appearance of hairs around the genitalia when a young man or woman became sexually mature. The word was later transferred to the bone of the os coxae the is positioned below the pubic hairs. The word coccygeus comes from the Greek kokkyx meaning “cuckoo,” because of the resemblance of the coccyx or tailbone to the beak of a cuckoo bird.
