CHAPTER 16 1) The antagonistic hormones that regulate the blood calcium level are calcitonin-parathormone. True 2)The hormone that raises blood sugar levels is insulin False 3)The endocrine structure that develops from the nervous system is the anterior pituitary. False 4)Both turn on factors (hormonal, humoral, and neural stimuli) and turn off factors (feedback inhibition and ʺ ʺ ʺ ʺ others) may be modulated by the activity of the nervous system. True 5) ACTH stimulates the adrenal cortex to release corticosteroid hormones. 6) In humans, melatonin may inhibit sexual maturation. True 7) LH in males is sometimes referred to as ICSH. True 8) The only known effect of prolactin in humans is to produce impotence in males. False 9) Oxytocin is a strong stimulant of uterine contractions. True 10) Follicle cells of the thyroid gland produce thyroglobulin, while follicle cells of the parathyroid produce calcitonin. False 11) The thyroid gland is embedded in the parathyroid tissue. False 12) The prime metabolic effect of cortisol is gluconeogenesis. True 13) The beta cells are the pancreatic islet cells that produce insulin. True 14) Type II diabetes lacks insulin activity False 15) Peptide hormones enter the target cells and elicit a response by mediating neurotransmitter effects. False 16) Calcitonin is a peptide hormone that has destructive effects on the skeletal system. False 17) Aldosterone is the most potent mineralocorticoid produced in the adrenals but the least abundant False 18) Atrial natriuretic peptide (ANP) is a hormone that controls blood pressure in part by increasing the urinary secretion of sodium. True 19) The thyroid gland is a large gland that controls metabolic functions throughout the life of an individual. True 20) Many hormones synthesized in the gastrointestinal tract are chemically identical to brain neurotransmitters. True 21) All of the following hormones are secreted by the adenohypophysis: ACTH, FSH, and LH. True 22) Iodine is an essential element required for the synthesis of thyroxine. True 23) The endocrine gland that is probably malfunctioning if a person has a high metabolic rate is the parathyroid. False 24) Growth hormone always exerts its influence by targeting other endocrine glands to produce hormones. False 25) Diabetes insipidus and diabetes mellitus are both caused by a genetic mutation involving the synthesis of insulin. False 26) The stimulus for calcitonin release is usually excessive amounts of growth hormone synthesis. False 27) Glucocorticoids are steroid hormones that usually enhance the immune responses when an individual is suffering from severe stress. False 28) Direct gene activation involves a second-messenger system. True 29) All peptide hormone synthesis requires gene activation that produces mRNA. True 30) Secretions of the adrenal glands control calcium metabolism. False 31) Negative feedback causes more hormone products to be released. False 32) Oxytocin is released by the posterior pituitary. True
