                                      FSH                                           (LH)

           In         a.  Stimulates the development          a.  Cause the rupture of the follicle 
           females       of the ovarian follicles.               release of the ovum  conversion of the
                      b.  Induces the secretion of               ovarian follicle into a corpus luteum

                         estrogen from the follicle              (yellow body).
                                                              b.  Induces secretion of estrogen &
                                                                 progesterone from the corpus luteum.

           In         Acts on the Sertoli cells of the        Acts on the Leydig cells of the testes to
           males      testes, which are involved with         stimulate secretion of testosterone.
                      production of sperm.


                                                              NB

           The release of FSH and LH is regulated by the hypothalamic releasing hormone,

                                  gonadotropin-releasing hormone (GnRH).


                             5-  Thyroid-stimulating hormone (TSH, thyrotropin)

            a.  Regulates the growth & metabolism of the thyroid gland.

            b.  Stimulates synthesis & release of the thyroid hormones  T3 & T4.

          The release of TSH from the thyrotrope cells of the adenohypophysis is induced by
                                    thyrotropin-releasing hormone (TRH).
