- Tumors that affect the pituitary can lead to decreases in some, but not all, hormones released by the pituitary. A patient with such a tumor exhibits fatigue, weight loss, and low blood sugar. This is probably due to lack of production of a. GH, which leads to loss of muscle mass. b. ACTH, which leads to loss of production of glucocorticoids. c. TSH, which leads to loss of production of thyroxin. d. ADH, which leads to excess urine production.arrow_forwardWhich of the following statements is NOT true about human growth hormone (hGH)? Select one: a. Excessive levels of hGH has been linked with diabetes mellitus. b. Genetically engineered hGH has been used safely to treat dwarfism. c. After the growth plate has sealed, increased levels of hGH results in a widening of the nose. d. hGH is produced in the hypothalamus and secreted by anterior pituitary.arrow_forwardWhich of the following is not a function of the endocrine system?
