The pelvis is a large bowl-shaped group of bones at the base of the abdomen. This section of the skeleton is made up of several bones fused and linked together. It surrounds and protects the soft organs inside the lower abdomen. The pelvis has many functions. It supports the intestines and bladder and the space in the middle allows waste from the intestines and bladder to leave the body In women, the pelvis supports the uterus as it expands to hold a growing baby and also provides the baby’s route out of the body during childbirth. Many muscles in the back, abdomen, and legs are anchored to the pelvis, helping to keep the body upright. The pelvis allows us to stand walk, and run without falling over.
The muscles of the pelvic floor wrap around and control the opening of your bladder and rectum. When there is an increase in abdominal pressure (for example when you cough, sneeze, laugh or jump), these muscles contract around your urethra and anus to prevent leakage. Equally as important, these muscles have to relax and lengthen to allow us to urinate or have bowel movements easily.
