Question

The growth hormone axis contains at least one example of a negative feedback loop. State True or False your answer:

a. True
b. False

Answer 1

a. True

Step-by-step explanation:

Classical studies suggest that growth hormone (GH) secretion is controlled by negative-feedback loops mediated by GH-releasing hormone (GHRH)- or somatostatin-expressing neurons. Catecholamines are known to alter GH secretion and neurons expressing TH are located in several brain areas containing GH-responsive cells.
