Neurons in the hypothalamus secrete thyroid-releasing hormone (TRH). TRH stimulates cells in the anterior pituitary 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 it have on TRH production?
It would double.
It would quadruple.
It would remain the same.
It would slow or stop.
