Hormone secretion can be stimulated and inhibited by: 1  Other hormones (stimulating- or releasing -hormones) 2  Plasma concentrations of ions or nutrients, as well as binding globulins. 3  Neurons and mental activity.  Environmental changes, e.g., of light or temperature.
This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland. This hormone production system is regulated by a negative feedback loop so that when the levels of the thyroid hormones, thyroxine and triiodothyronine increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone.
