  What are the consequences of over secretion and under secretion of growth hormone? How is timing and amount of a hormone released regulated?

Answer:

  Over of growth hormone causes Gigantism                                                                                                                         (1) While under secretion of growth hormone causes Dwarfism                                                                                       (1) Feedback mechanism regulates the timing and amount of hormone released. For example, after having meals, blood sugar level rises. Pancreas responds by producing more insulin. When sugar level falls, insulin secretion also falls down and secretion of glycogen increases.                        (1)
