    • •occurs before the child is born
    • •sometimes the mother's first sign of impending labor
    • •when the "water breaks"
  32. labor
    • process by which the child is expelled from the uterus
    • •time from the beginning of cervical dilation to delivery of the placenta
    • •four stages (1)cervical dilation; begins with onset of regular uterine contractions, ends when cervical opening is fully dilated (2) expulsion; extends until complete expulsion of the infant (3) placental; extends until the placenta is expelled (4) postpartum; not everyone recognizes as a stage of labor, hour or two after delivery when uterine tone is established
  33. effacement
    • shortening and thinning of the cervix during labor
