The pelvis also called the bony pelvis or the pelvic girdle, is a basin-shaped complex of bones. It connects the trunk of the body to the legs, supports the balance of the trunk, and contains and supports the intestines, the urinary bladder, and the internal sex organs.
The pair of bones that form the pelvic girdle are paired hipbones that are connected at the anterior pubic symphysis and the posterior sacroiliac joint with the sacrum; each is made up of three bones - the ilium that is lateral to the sternum and gives the width of the hips; the ischium, which sits inferior to the ilium and in the posterior, the ischium or 'sit' bones are where the weight falls while sitting; In the anterior medial to the ischium and ilium is the pubic bone. In early adulthood, each pair of three bones form together to create the cup-shaped socket of the hip joint for the head of the femur.
