E. Regulating TSH produced by the anterior pituitary gland - ANSWER The
answers are B, C, and E. T3 and T4 burn calories (not store them) and
increases body temperature (not decrease).
A patient is admitted with complaints of palpations, excessive sweating, and
unable to tolerate heat. In addition, the patient voices concern about how her
