Sensory Nerves That Detect the Pressure of the Fetal Head

Sensory nerves that detect the pressure of the fetal head on the cervix send signals that stimulate the release of oxytocin from the pituitary. As a result,

A) glands in the breast tissue start producing milk to feed the infant.
B) the endometrium of the uterus is stimulated, causing the fetus and the placenta to be released from the uterine wall.
C) the myometrium of the uterus is inhibited, which reduces the pressure on the cervix.
D) contractions of the myometrium are stimulated, which further increases pressure on the cervix.
E) oxytocin acts like a natural opiate to inhibit subsequent transmission of pain signals.
