Coccygeus
Coccygeus
Coccygeus (pronunciation: /kɒkˈsiːdʒiəs/) is a muscle that is part of the pelvic diaphragm, which supports the pelvic organs.
Etymology
The term "coccygeus" is derived from the Greek word "kokkyx", which means "cuckoo". It was named so because the coccyx, to which the muscle is attached, resembles the beak of a cuckoo bird.
Anatomy
The coccygeus muscle extends from the ischial spine to the sacrum and coccyx. It is located posterior to the levator ani muscle and is sometimes considered part of that muscle. However, it is separated from the levator ani by the sacrotuberous ligament.
Function
The coccygeus, along with the levator ani, forms the pelvic diaphragm. It helps to support the pelvic organs and assists in maintaining fecal continence. It also plays a role in childbirth, as it can help to control the descent of the baby through the birth canal.
