COCCYGEUS

The coccygeus (ischiococcygeus) is a triangular muscle located on each side of the pelvis. It originates from the ischium and inserts in the coccyx and sacrum. It closes the back part of the outlet of the pelvis. The coccygeus muscle is innervated by the third and fourth sacral nerves. This muscle raises and supports the coccyx.
