Coccygeus is a term that refers to the muscles located in the pelvic region. These muscles play a vital role in supporting the organs located in the pelvic area, such as the bladder, uterus, and rectum. The coccygeus muscle is also known as the ischiococcygeus muscle, and it is often referred to as the levator ani muscle. Other synonymous terms for the coccygeus muscle include the pubococcygeus muscle and the iliococcygeus muscle. Regardless of its name, this muscle is crucial to maintain proper pelvic floor structure and prevent issues such as urinary incontinence and pelvic organ prolapse in men and women.
