For a greater understanding of the pelvic floor muscle within the pelvic girdle, it is the area between the pubic bone in the front and the tail bone in the back. There are several small muscles, nerves, and other soft tissues that form a sling creating support to the abdominal and pelvic organs to include the bladder, uterus and bowel. When the muscles are weak, they cannot stop leakage or when they are too tense you might have incomplete voiding and/or sexual pain or constipation.
