The pelvic floor muscles are a sling of muscles attached to the bottom rim of the pelvis. They attach to the pubic bone anteriorly and the coccyx posteriorly. The pelvic floor muscles support the pelvic organs and help maintain good bladder and bowel function as well as guiding the baby’s head during birth. Three openings p[ass through the pelvic floor – the urethra, the vagina and the anus. When the pelvic floor muscles are contracted the three openings will tighten and a woman should also feel that the pelvic organs are lifting up higher inside.
