For demonstrating the progress of the fetus through the maternal pelvis during childbirth, this functional reproduction consists of an actual cast of the female pelvic skeleton with movable pubic symphysis, complete with sacrum, coccyx and two lumbar vertebrae, articulated to accommodate passage of a full-term fetal skull replica mounted on an omnipositioning flexible gooseneck support. The pelvis is mounted on a rectangular base.
