he pelvis is made up of a number of different bones: on the back the "sacrum" (sacrum), on both sides a 'ilium' (ilium) and in front of the abdomen, the "pubes". The sacrum forms the lower part of the spine. 

''At the rear of the back is the sacrum on both sides connected to the ilium. This connection is called the sacroiliac joint, often abbreviated as SI joint. These joints are located on the back layer at the location of the two small holes on either side of the spine. The pubic bone is the continuation of the iliac to the front of the body. The connection between the pubic bones in the lower mid-abdomen called symphysis. 

The connections between the different parts of the pelvic bones at the symphysis and the sacroiliac joint are made of cartilage. Around these compounds, there are elastic bands and hairstyles to strengthen them. In pregnancy, these compounds are smoother and more elastic. This can be seen as a preparation for childbirth: this child should come through because the pelvis outward. A basin that is less rigid and a bit 'yields' can be helpful. The process of loosening of the connections between the pelvic bones, makes them to be more volatile relative to one another. This is sometimes accompanied by pain.
Different symptoms may be related to the pelvic floor. Examples are: difficulty urinary retention, feel that there is something out of the sheath outside drops, losing to suffer constipation or even feces. 
The pelvic floor, bladder, bowel and vagina are close to each other. Therefore, often simultaneously several complaints. Many women feel that there is little to do with their complaints. 

2 Construction and operation of the pelvic floor 

The pelvic floor is located at the bottom of the basin and forms together with the bones of the pelvis, the lower end of the abdominal cavity.Because of the pelvic floor run the bladder and urethra (urethra), the sheath (vagina) and the end of the large intestine (rectum). They are held in place by the pelvic floor muscles and ligaments attached to the bones of the pelvis. With movements like coughing or laughing, the pressure in the abdomen. The pelvic floor holds over all the organs in place. Nerves, ligaments and muscles of the pelvic floor will ensure that you can close if you want. Bladder, bowel and vagina off By relaxing the pelvic floor muscles can urinate, intercourse or bowel movements. To get rid of urine and feces should also bladder and colon normally and can contract and relax. 
In summary therefore ensures the pelvic floor is for: 

  • the abdominal cavity is closed, so that abdominal organs do not come out
  • urine and feces that you do not lose unwanted
  • you if you want it you can have urination and defecation
  • that you may have fellowship
