WebbThyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine (T 3) and thyroxine (T 4).They are tyrosine-based hormones that are primarily responsible for regulation of … WebbTSH then induces production of thyroxine (T4) by the thyroid. In response to the concentration of free T4, which influences the amount of triiodothyronine (T3) produced in each site, both the hypothalamus and the pituitary alter production of TrH and TSH, respectively. Elevated free T4 inhibits production, while low free T4 stimulates production.
