1 Created by Boundless Both controlled by the posterior pituitary gland, vasopressin ___________ while oxytocin ____________. A regulates water retention ability in the body; regulates bonding behaviors in the body B regulates heart function; regulates maternal bonding C all of these answers D regulates diuretic responses in the body; regulates behaviors linked to blood vessel constriction 2 Created by Boundless Hormone production by the anterior pituitary gland is controlled by the hypothalamus: A through the use of regulatory hormones produced by the anterior pituitary gland itself. B through the use of regulatory hormones controlled by negative feedback mechanisms. C through the release of vasopressin, which is made by the posterior pituitary gland. D through the production of inhibiting hormones, which are then controlled by positive feedback. 3 Created by Boundless Hormones produced by the anterior pituitary gland: A travel from the posterior pituitary gland to the hypothalamus. B act only as inhibiting hormones. C control the functioning of other organs. D are referred to as tropical hormones because of their role in high temperature regulation. 4 Created by Boundless Production of T3 and calcitonin differ in: A their regulation by the thyroid gland. B their regulation by the thyroid stimulating hormone. C their regulation by calcium. D their regulation by the T4 hormone. 5 Created by Boundless How does parathyroid hormone maintain homeostasis? 6 A Calcium levels are maintained by the release of oxyphil cells, which disrupt calcitonin effects. B Parathyroid hormone works in complimentary tandem with calcitonin. C Chief cells prevent the release of parathyroid hormones to instigate Ca2+ production via calcitonin. D Parathyroid hormone works in opposition to calcitonin to avoid insufficient amounts of calcium. Created by Boundless How do parathyroid glands regulate calcium levels in the blood? A A deficiency in parathyroid hormone causes a calcium releasing event. B Gland regulation of oxyphil cells results in an increase or decrease of calcium in the blood. C A decreased level of phosphorus triggers calcium release from bones. D They produce parathyroid hormone which releases stored calcium from bones to the blood. 7 Created by Boundless Which of the following statements is correct about adrenal gland hormone production? A The adrenal cortex produces mineralocorticoids and glucocorticoids. B Blood glucose levels are regulated by mineralocorticoids. C Sodium and water balance are regulated by hormones produced in the adrenal medulla. D The adrenal medulla produces cortisol and corticosterone hormones. 8 Created by Boundless Both main types of hormones produced by the pancreas: A are both produced by alpha cells. B secrete pancreatic juice that help with nutrient absorption. C have roles in food digestion. D regulate blood glucose levels. 9 Created by Boundless Which of the following statements about gonads is true? A The ovaries produce testosterone, which regulates the female sex organs. B The gonads are responsible for the production of hormones that regulate sexual characteristics. C Estrogen regulates sex characteristic development in females; progesterone does the same in males. D All of these statements are true. 10 Created by Boundless How is melatonin production regulated by the pineal gland? A Melatonin secretion is released in the presence of free radicals. B All of these answers C Melatonin secretion is regulated by photoperiods. D Melatonin production increases during the daytime. 11 Created by Boundless What types of endocrine functions can be seen in organs whose primary role is nonendocrine related? A These organs can display endocrine functions in the event of endocrine gland malfunction. B All of these answers C Many of these organs produce or release hormones that are involved in function regulation. D All of these organs possess endocrine cells that produce hormones.
