Negative feedback system in hypothyroidism - CORRECT ANSWER -Production of T3 and T3 by
the hypothalamus and pituitary gland
TRH - CORRECT ANSWER -from the hypothalamus controls the release of TSH
TSH (negative feedback loop) - CORRECT ANSWER -acts as the gauge for the hypothalamus to
know if it needs more or less TRH and subsequently more or less TSH
