Final answer:
The ischio coccygeus, or coccygeus muscle, is a small muscle in the pelvic region that supports pelvic organs and helps maintain continence.
Step-by-step explanation:
The ischio coccygeus, also known as the coccygeus muscle, is a small triangular muscle located in the pelvic region. It is one of the two muscles that make up the pelvic diaphragm, along with the levator ani muscle. The main action of the ischio coccygeus is to support the pelvic organs and help maintain continence.
The ischio coccygeus muscle helps in stabilizing the organs in the pelvis, including the bladder, uterus, and rectum. It also assists in controlling the movements of the coccyx, or tailbone. This muscle plays a crucial role in maintaining proper pelvic floor function and preventing conditions like pelvic organ prolapse.
