The Two Governors Of Our Body:
                            The Hypothalamus And The Pituitary Gland


            no clock in the hypothalamus, but com-
            paring it to a clock is the best way to
            describe how cells wait for years to go
            into action at just the right time.
                 How do the cells that make up the
            hypothalamus know that the right time
            has come? The scientific world has not
            yet been able to explain how a small
            piece of flesh can act in such a con-
            scious and programmed way.    10  It is
            likely that the details of this system will
            be understood as years go on, and
            when they are understood, they will
            provide another proof of the perfection   Because of its "hidden" clock,
                                                      the brain's hypothalamus area
            of God's creation.                        "understands" when a per-
                 With the sounding of the alarm,      son's adolescence has started.
                                                      And this clock operates in
            the hypothalamus secretes the special     every human being without
            GnRH hormone. This hormone sends a        breaking down or stopping.
            command to the pituitary gland to se-
            crete two hormones, the Follicle Stimulating Hormone (FSH) and the
            Luteinizing Hormone (LH).
                 These two hormones have very special functions and marvelous
            abilities. Each one begins the process of physical differentiation and
            development of the male and female body. The FSH and the LH hor-
            mones have been designed to effect the areas in which this change will
            occur and they act as if they knew very well what they have to do.
                 In the female body, the FSH hormone causes the maturation and
            development of eggs in the ovaries and ensures the secretion of the very
            important estrogen hormones by this area.
                 The FSH hormone is secreted according to the same formula in the
            male body, but here it has totally different effects; it stimulates the cells in
            the testes and initiates the production of sperm.
