Bipedalism separates humans from most other animal species, but results in significant physiologic challenges, particularly with respect to the maintenance of pregnancy and induction of parturition. A contracted lower uterine segment (LUS) and a relaxed uterine fundal myometrium (FUN) during pregnancy are required to prevent pressure on the cervix from the fetal head due to gravity. With the onset of labor, this regionalization of myometrial function must be reversed, allowing descent of the fetus, dilation of the cervix, and expulsion of the fetus through the birth canal. However, the molecular mechanisms remain unclear.
