what is the function of the pelvis
Pelvis can be regarded as a basin with holes in its walls. The structure of the basin is composed of four bones which are joined by four joints. The bones are: 1  Two hip bones: These form the lateral and anterior walls of the bony pelvis. 2  Sacrum: It forms most of the posterior wall. 3  Coccyx: It is a small bone that forms the lower part of posterior wall.
