Abnormal function of the endocrine system may result from a number of different causes. These pathophysiological states of the endocrine system or endocrinopathies may be caused by the absence of hormone, underproduction of hormone, overproduction of hormone, abnormal hormone transport in blood, absence or abnormal function of hormone receptors, or absence or abnormal function of one or more of the cytoplasmic signaling cascades required for normal hormone action. Test your basic knowledge of endocrine pathophysiology by taking this simple quiz.

(1) When considering the endocrine pathophysiology of the hypothalamus, abnormal states arising from underactivity of the hypothalamus are considerably more common than those arising from overactivity of the hypothalamus.
(2) Disruption of the pulsatile secretory pattern of the following hormone can lead to amenorrhea:
(3) If the hypothalamus is damaged, due to a tumor or surgery, the following are likely to be observed:
