The Two Governors Of Our Body:
The Hypothalamus And The Pituitary Gland
Who decides to apply the brake? Estrogen, a hormone produced
during pregnancy, ensures that the brake is applied by producing PIH.
When the baby is born, the amount of estrogen secreted is reduced,
which also reduces the amount of PIH. This is like the foot slowly releas-
ing the brake and the car moving down the hill. In this way, the produc-
tion of prolactin slowly begins and activates the milk glands to produce
mother's milk.
Here we see a real wonder of creation. Thanks to this design, the
production of milk is prevented during the first months of pregnancy.
Consider this whole system carefully:
1. Where do the cells of the pituitary gland that produce prolactin
know the milk glands from? With what conscious intelligence do they
give the command to the milk producing cells to produce milk?
2. How do the hormones that prevent the production of prolactin
before birth know that the time for milk production has not quite come?
