Quizplus · Accepted Answer

Stretching of the cervix (as occurs during labor) stimulates the release of oxytocin from the posterior pituitary gland, which in turn increases the contraction strength of the uterus and can lead to an increase in the levels of oxytocin in the blood. This mechanism is part of the positive feedback loop that accelerates labor.
