EXAM
The first stage, dilation of the cervix, is the time it takes for the mother's cervix
to dilate to ten centimeters. During this stage the uterus contracts, which pushes
the baby's head against the cervix causing it to dilate (widen). This stage of
labor is the longest, lasting, on average 6-10 hours. Oxytocin is a hormone that
is released from the posterior pituitary gland to stimulate contractions in the
myometrium of the uterus. As contractions continue, oxytocin is increasingly
released until the baby is born.
