Neurons in the hypothalamus secrete thyroid-releasing hormone (TRH). TRH stimulates cells in the anterior Picture wary to secrete thyroid-stimulating hormone (TSH). TSH binds to receptors on epithelial cells in the thyroid gland, stimulating synthesis and secretion of thyroid hormones (THs). When the concentration of THs reaches 8 ng/mL, the neurons in the hypothalamus are inhibited from producing TRH. If a person was given an injection of 52 ng/mL, TSH, what effect would have on TRH production?
A.) It would double.
B.) It would quadrupled.
C.) It would remain the same.
D.) It would slow or stop.
