Figure is attached below.
<h3><u>Explanation:</u></h3>
Pelvic girdle is the largest complex bone system of human body. It's formed by fusion of 5 sacral vertebrae and 4 coccygeal vertebrae forming sacrum, the iilium, ischium, and the pubic bone. The iilium, ischium and pubis fuses to form single bone called os inominatum.
Two os inominata are joined with sacrum on both sides.
In the iilium, there are groves for the sciatic nerve which lets the sciatic nerve to pass from lumber region into the legs.
